Even good posters have particular issues they can't help seeming retarded on. ^LOL...so openly expressing the affirmation of a maligned and discriminated against group, in a parade that celebrates many different subgroups within a larger one, is objectively "wrong" according to you.
Why cut off my post? Im off the opinion that the LGBT is overreaching here, IMO. The fact that you feel so passionately about them seeking representation in a parade of all things, says just as much about you as it does them.
In your case, this is one. And you don't have to be passionate to realize the blatant trollinesq nature of the lgbt here.
