A look into history:

But I see most already know they are historically been around.
I believe Alix was stating she had no issues with any sexualism or genderism, so if she slipped a word, I wont fault her. Cause I believe she is saying she loves all of them despite a word mix up or not. 
I don't mind transgender being in the game, they are another person to talk to and learn from.
I know somethings I know cause of people I talked to directly instead of making my own mind up on words that was indirect. Meaning, I cant judge gay men by few people I met, cause they hate gay men themselves, I learned from a few gay men on what they was like instead.
Direct over bias, I probably am not saying this all right.
Sorry, sometimes I misconstrue my own words. I make my mind up on facts of the person and not just go by what other people say or think.
