I have two "problems" with this whole phenomenon. One of them is semantic. It seems that there will always be another letter added to the chain by some group claiming a different sort of victimhood. No matter which letters one decides to use, there will always be those who say it is incomplete because their pet group was omitted.
The population we refer to as "African Americans" have a history of changing their preferred words of reference. "Negro" used to be formal, with "colored" being entirely acceptable. If one Negro called another Negro "Black," them was fighting words, and a blatant insult to the person described. Then it became Afro-American and "Black." Now it's African American...which could change any day now, if it hasn't changed already (and I missed it).
The point is, that community has driven the bus with respect to public reference to their moniker. The LG...community should do the same. I realized "Sexually Fucked-Up" is probably a little harsh, but they need to come up with a word that they can all agree on, just for semantic convenience. Sexual Irregulars?
Second, the combining of some of the groups is illogical. If I am a man and I sexually prefer other men, that is one orientation. If I am a biological man who thinks he is really a woman, and therefore likes other men, that is a whole different phenomenon. And where does Bruce Jenner fit in? He claims to be a woman, but I understand he has a "girlfriend" - is he a LESBIAN? Jesus Fucking Christ!
