Boortz always seemed to be a bit against Christianity. Maybe i am wrong.
Boortz loves to "tweak the noses" of any group of people who have a message to express in ways that is over the top. Yes, sometimes seemed to be throwing rocks and Christianity, but if you stayed with his explanation without loosing your cool, you soon realized he was just making life hard for people who do a cheap, shoddy presentation of their faith. Boortz tends to be and "equal opportunity employer" of lampooning folks.
BUT, there are a few topics which he seems to have serious feelings about where he also can be lampooned.
