The Church has done bad things but, even non-believers have to acknowledge that Western society is built on Christian foundations.
Paul wrote in his Second Epistle to Timothy: In the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers ... Heady, high-minded, lovers of pleasures more than lovers of God ... Having a form of godliness, but denying the power thereof.
A form of godliness is a good way of putting it: You elevate your pleasures [i.e. homosexuality, free sex] and their attendant paraphernalia , condoms, abortion clinics into a new creed of tolerance and diversity that eventually supplants Christian morality. On the matter of AIDS and homophobia, the gay crowd has a good slogan: Silence = acceptance. We should start screaming at the top of our lungs, and even then I do not know if it will help.
Shalom.
