That's quite funny and ironic, since it's actually somewhat correct in some sense. Freedom of thought is indeed Zevist, at least way more than it is "of Jesus".
Free thinking can also lead people to the realization that "the Devil" actually is the real God, and so by attacking free thinking they keep people in place.
This also goes hand in hand with how they attack yoga, since a raised serpent leads one to become strong enough to have a mind of ones own, and a stronger power of thought.
Strong enough to see through their bullshit "religion".
I don't think that any Zevism have to waste their Time and energy or even though about this kind of people, me in person have no empathy to people who have no souls or very dirty ones.
