The only reason

"The only reason that Jews are in pornography is that we think Christ sucks. Catholicism sucks. We don't believe in authoritarianism. Pornography thus becomes a way of defiling Christian culture and as it penetrates to the very heart of the American mainstream, more charged."

-- Al Goldstein, Pornographer

I doubt Jews care about Christianity. More like pornography makes them a lot of money and helps advancing Cultural Marxism.

Then pornography isn't exclusively Jewish business, just because it'is so easy to produce nowadays.
