Homosexuality is not a "lifestyle" option
It is an innate sexual orientation
Yeah...been down that road and I can't definitively disagree with you...it does seem to be little more than a fad faze with some people though.
I've literally heard people talk about using their college time for instance as a period to explore their sexuality. As if one goes through a period in which they are free to experiment like nothing has purpose or meaning other than for the experience.
However...have you considered that IF its an innate sexual orientation which we should sympathize with - or perhaps respect is a better term - that is may just be that some people have an innate abhorrence to that orientation that should also be respected?
Perhaps it shouldn't be labeled homophobic but instinctual then? Should we condemn what is instinctual? If so then we are back to the possibility of rightfully condemning homosexuality.
I'm not sure how we should resolve such things other than starting by trying to understand why someone is behaving in a manner that someone else deems to be homophobic.
