From my point of view historically these people have existed, and we have evidence that points to an explanation that, for at least for some people, doesn't involve subjective feelings, and doesn't involve delusion. Their brains are physically different.
This is factually incorrect. On the contrary, there were hypotheses that they were different, but every scientific study done so far has not found any evidence of that. For example, there was a twins study (where 1 twin is heterosexual and the other homosexual) that came out about 6 years ago and their conclusion was (paraphrasing) "well, some people like broccoli, some people do not."
The irony is that the argument has shifted: when I was younger, it was "they are born that way". Now that studies have not found any proof of that, it has shifted to "let them choose to be what they want to be!" Personally, I don't care what other people do with their lives (I have enough fun destroying my own life ... no need to worry about someone else destroying theirs!) But I do find it interesting to see how people try to justify their choices in life.
Well, I don't know much about it honestly.
After some limited googling, and wiki-ing, it seems there are studies that support the idea that the brains are physically different.
As for twin studies, I'm not convinced that a single twin study overturned everything I thought I'd read a long time ago that identical twins, even when raised separately, were more likely to both be one way or the other. Of course not every set is, but if most are then it points to genetics being a factor.
Sure, society sometimes goes too far, and has to self correct. Like I said I'm not in love with one ideology or the other. The main thing for me is what the basis is.
If people are guided by logic and empathy then I don't fear whatever the future holds. If we're guided by fear and bigotry then I can't imagine things changing for the better.
You make it sound like those groups of traits are mutually exclusive Additionally, if you are guided by logic, you are rarely guided by empathy. Emotional responses (i.e. empathy) tend to be illogical more often than not.
Not exactly sure what you mean, but I will say some on the left are totally nuts, and fascists, and awful human beings, full of hate and bigotry, for sure.
As for empathy and logic, yeah, humans are pretty mixed up. Far from perfect for sure, but IMO we have to try our best to balance these things. A good life (or good society) can't be lived totally devoted to either one or the other IMO.
