Well, let's make this clear: to be different from the rest of the people doesn't mean to be abnormal. Many great persons of the past, who did great things where 'weird'. So it depends from what you consider normal and what you, or the society where you live, consider weird. In a conformist and irrational world, to be considered abnormal may be a sign of normality. There are many things of this world and this society that makes no sense.
Then there are some mad men who play chess. But that's a problem of them, not of chess.
=) hope you get what I'm trying to say in my poor english, lol
Wow This topic seems really negative, both for chess and for Chess players in general.
Anything in life that we pursue with obsession can lead to problems. Players like Fischer, who may seem mad on the outside, usually have some kind of history of seclusion or personal hardship.
I personally went through a 16 years phase, if not longer, of constantly playing computer games all day every day. This wasn't healthy and caused a lot of problems for me, both mental and physical, I was afraid to leave the house it got so bad.
I became very unsociable and paranoid about everyone around me, fortunately I was able to say enough is enough and pull myself from my own demise.
I was both completely compelled with the gaming industry and felt very passionately about it at the time. I had no other interests, really. It's not just computers this can happen with, even though it was an addiction, there are many strange ways we can become obsessed with various activities in life.
In chess, a perfect example is Fischer, his life was far from normal when he was a small child. His father disappearing, his mother, Regina who wrapped up in her own activities to notice her son and his needs.
He escaped it all, through the chess board. Having discovered chess at an early age and becoming compelled by the game, it eventually made him paranoid in his later years.
We cannot blame the tools when we misuse them. Would you blame glue and ban it because some people decide to sniff it? Would you ban beer because a small minority of people become addicted to it?
The key word here is balance, we need to approach everything in life with moderation and not abuse the things around us.
