Well:So I change my gender as a female and someone else who is female tries to discuss with me about female stuff.
Someone likes my post AND because I am female and gets an impression but then finds out I am a guy.
A desperate male thinks I am a female and hits on me,he gets disappointed.
A guy acts as female and starts to act like a femminazi..irony
If one is a female I am talking to I would refer her as she and if he is guy I would refer him as he while discussing a matter one's gender might be used to judge a person's behavior. Also swearing at a person,you swear at one you call one a ****** and he turns out to be a female.I would have rather used *****.
Then it depends on the intentions of the guy and how a female would feel about it. Also, this is the internet, you need to be 'street smart' about most things here, lest you be out in a nasty situation.
Likes the post because it's a female, you mean? Depends on what forum it is etc. NB isn't primarily a dating site, for example.
He needs to learn more about the internet.
Depends on what they're being particular about.
Might. What about transvestites? They may feel, not only behave, in a way that is particular to a certain gender.
I don't think the discontent on your side would go unnoticed either way.
I tried to retort in order of what you wrote.
