Good response, Damiana. I, too, have enjoyed reading the responses. I think the only time gender identity is important to me is when it concerns a person with whom I want to have sex. Otherwise, it's irrelevant. I've known gay men who have admired my chest ("would like to have that body" - I look like a [male] swimmer [which I am]), and women who have appreciated my company with or without boobs. The latter I've enjoyed on many levels, the former I've been friends with because sexual relationships with them were not part of the possible world.
So, I guess if I had a pet peeve, it would be when sex or gender presentation was considered important when it was really irrelevant. In a job interview (unless it was for the position of concubine or hooker) sex/gender presentation should be irrelevant.
