The problem is that more simple minded people who are actually conservative, as they want to conserve society as it is, will easily fall for the propaganda and vote for a party that is out to destroy what they want to conserve.

The real problem is that “conserve society as it is” was always a lie, unless the “as it is” you’re talking about happened to be monarchy. Conservatism, as an ideology, was founded in support of monarchism. A society run by an aristocratic elite has always been the thing they’re trying to conserve.
