I agree that Christian and Jewish scripture calls on believers not to engage in gay sex. But many secularists (including practicing Christians and Jews of the liberal persuasion) believe those passages are not binding on the faithful. It is not for the Republican Party to resolve the religious war between libs and fundy's, but to put out a clear conservative message and if gays like the message and vote Republican, its just fine with me. Apparently about a third do.
I disagree with Horowitz about a "gay agenda." Its a bad term because it labels all gays, but there is an agenda by the radical gay public interest groups to extend Civil Rights Act protection to gays, allow gay marriage and to use this special status to impose acceptance and secularism, to run practicing Christians from out of the schools, government and public life. Not all gays agree with this agenda.
Name one.
