Bless you brother but that's utterly ignorant and foolish of you. 
 the word 'gay' up until the 80s generally meant careless, carefree, happy, you could have a gay ol' time back in them times. 
 I suppose homosexuals have adopted that word to self-consciously attempt to reassure themselves, I won't make any broad statements on this website, knowing it's tilt, but 'homosexual' is the neutral term, sodomite, transgressor or some other word would be non-'neutral' words, there're profanities too but that's of the devil, and only for them that truly are without love for the sinners.
