What questions have I left unanswered? Why homosexuality requires a change in society?
What makes homosexuality (in particular) something that we have to change our society and culture so radically and fundamentally in order to attempt normalizing it?.
The odd thing is, that you even believe that our society and culture are being radically and fundamentally changed just because our society is now treating homosexuals equally before the law.
No one is fundamentally changing your life in the United States. What has been changing is that decades- even centuries of legal discrimination have been gradually eliminated. None of which affect you personally. Or any non-gay American.
What makes you think that Americans who are homosexuals do not deserve to be treated equally by the law?
