Well, evidence would lead one to conclude that men are better at chess than women grobe. There is certainly no evidence to lead one to think women are better. If they were equal why is there different (lower) requirements for them to get FIDE titles ? Why are there women's competitions ? Why cant they compete with men if they are better or equal ? It certainly seems fide thinks men are better. There is nothing preventing a woman from becoming world chess champion and yet one hasnt even come close yet. I think PC types get upset because they equate saying men are better at chess with saying men are smarter, but I dont believe this at all. I think chess is much more about interests/passion/understanding and how competitive one is. I think men are more likely to be fanatics in whatever interests them than women are. Women are more practical than men. ( in general )
Boys are better at chess than Girls.
It is true that males aren't as susceptible to the demands of motherhood......
Look unless some of us are geneticists or biologists we don't really know all the exact differences between men and women. Reb as you pointed out, NO ONE can argue that women are as physically strong (in general athletic) as men.
The 'PC Birds' will grant the physical difference but say mentally we all have the same capabilites. My question is how do you know? If the male body and female body are so different, how do you know the brain's aren't? I'm not saying they are that different, but just saying 'oh we all have the same mental capabilites' is a pretty shaky way to look at it.
I'm just saying I would expect men and women to have different strengths and wekanesses (in general) when it comes to mental processes. Like Grobe said, I'm not qualified to know what they are (I can offer my guesses) so I'm not going to offer facts, but its pretty naive to just assume men and women think exactly alike.
Well, one alternate explanation FIDE's stance regarding titles and segregated competition is that without those WGMs out there there wouldn't be as many high profile females out there at the top of the chess world to serve as examples for other women who are considering taking up the game seriously.
I'm glad to see the conversation turning far more rational.

It's pretty naive to profess to know what these differences are in general or if they even exist -- I'm not saying that it's not possible that men are better than women at chess, I'm just saying that those making the claim (or any related claim of certainty with respect to this issue, including equality) are doing so on a pretty unfounded basis.
I can tell you from my own personal experience I have always been more fanatical about interests/hobbies in my life than any female I ever met. I can also tell you that the women in my life constantly scolded me for my fanaticism ...... 
Yeah, I hear about it daily.

Why doesnt this surprise me ?! 
The bottom line is that having the opinion "Men are better than women at chess" is perfectly valid, and if you have the credentials (meaning you have really really studied this stuff) you may propose it is a fact.
Just jumping in and saying men are better than women because....flimsy premise # 29.... is not good enough, (pointless might be a better word here)

Interestingly, if we were to take this at face value (that men are generally more fanatical and prone to becomming obsessed with a hobby than women) it offers another explanation for the abberation we see at the top levels of the game that doesn't necessarily invoke a difference in innate chess abilities: that is, the commitment and obsession required to reach the top level of the game is more often exhibited by men than it is women and this is why there are disproportionately more male GMs than there are female ones.

Am I that transparent?

Yep !
not only in chess,in everything
And who gives birth to those GM's?
I assume your mainly joking anyway, but this line of reasoning clearly doesn't work because women also give birth to big hulking lineman with names like Moose and Bubba.
Please dont over analyze this post. And of course it works because women do give birth.
Enough of the silliness. Bobby Fischer said he could give any female chess player a Knight and still win easily! This is undeniable proof that men must be better than girls.
If Bobby Fischer gave any GM Female a knight today he would get his ass whipped. That may have been partially true in his day, but not these days.
This is what he said:
"They're all weak, all women. They're stupid compared to men. They shouldn't play chess, you know. They're like beginners. They lose every single game against a man. There isn't a woman player in the world I can't give knight-odds to and still beat."
1962, Harper's Magazine
I think that by the time Fischer passed, he realized that women had com a long way.
See:
Zhaoqin Peng: “About ten years ago I played a few Chess960 games with Bobby Fischer in Budapest. Svetozar Gligoric took me to Budapest, where I met Fischer. He did not want to play classical chess, only Chess960. We just played a few blitz games, I even managed to win a few, and I liked it a lot.

Susan Polgar the oldest Polgar sister says she had very good results against Fischer and implicates revealing the score would embarrass him.
"I had very good results against Bobby. But the final score is something I would never reveal unless Bobby consents. Trust is something that is very important to him."

You can't possibly be serious. Some dude's opinion is "proof". 
He cleary wasn't serious. Sometimes sarcasm is hard to detect, this time its shamefully obvious
The problem is you can't simply compare outliers (GMs) to draw conclusions about populations as a whole, even if you attempt to correlate this back to that population by, say, comparing relative population sizes between the outlier samples and the whole population.
It may be that there are disproportionately more male GMs than female GMs, but all this means is that there are more outliers. It doesn't rule out possibilities such as your average female in fact being better than your average male, and also doesn't take into consideration other possible explanations that may not have to do with innate chess abilities (the demands of motherhood derailing potential female GMs before they reach that title for example -- something males aren't as susceptible to).
