Abortion, pornography, the sexual de-volution (sorry "revolution"), gay privilege, and all those other things that the Left worships but run counter to God's will.
The Left hates religion because religion competes with the Leftist elites for power and influence. That's why dictatorships so frequently either eliminate religion or make themselves the subject of it. Dictators cannot abide competition. Since a large majority of academics are Leftists, and are fully willing to submit themselves and the rest of us to a Leftist autocracy, they are fully complicit in the rejection of religion from education.
