Do they? Highly debatable, I'm not sure how you can speak for all human beings. Certainly it can be the case when some people adopt different behavior towards the opposite sex that it's despicable. Also, surely it's not possible in some cases of gender self-identity to define an 'opposite'.

How uncomfortable does it feel if you pass a comment on someone assuming the person's gender and it turns out otherwise?

If that scenario makes you uncomfortable perhaps it's better not to pass the comment.

Let me site a good example for your benefit.
I did'nt know you are a man until yesterday!
Now, do you understand?

No. I understand that in this post and your previous reply you make a good case for why you feel more comfortable knowing the gender of another member, and how that is a help for you in judging what behavior you wish to adopt. However I still see nothing that addresses the question of why it is a requirement. If it is deemed a requirement then that is presumably because it is necessary. I don't understand what, for the functioning of this forum, makes stating ones gender self-identity a necessity?
