On a side note, where was your "friend"? He (I am guessing it was a guy) should have either stood up for you, or at least told you to ignore them, because they are jerks. I once made all warriors drop from a 40 man in vanilla, because the druids were harassing a rogue who was a female in real life and the raid leaders did nothing. She was too afraid to leave the raid, but when all the tanks and best dds in raid dropped, that got everyones attention. She was 35 years old at the time and an accomplished writer for the biggest gaming magazine in our country, but sexist remarks from a bunch of kids got to her. This is something we men will never experience, but should be aware of. There is no harmless sexism.
In case of jerks, /leave.
PS. Neo-feminism, led by angry lesbians, who by definition hate men, makes it harder for us to stand up for women.
