Not saying anything bad about you at all, but I think this is a perfect example of a really common logical fallacy that we on the lefter side of things tend to make. Lots of us (more often than not, myself included) that anybody on the conservative side of things is simply conservative due to lack of information.

Unfortunately, I don't think that's the case. As a transplant to the South, I think the reality is that not only do plenty of supporters know that, even more very literally don't care.

Say for instance that you think abortion is murder. Nevermind all the reasons you're wrong or all the constitutional reasons you can't possibly make laws based off that without grossly violating women's civil rights. Just say you believe abortion under any circumstances is murder. Why would you care if you're in the minority? In that case, you don't want majority rule. You don't want popular opinion to "win." You will actively support people who want to tear down democracy and separation of powers, because you believe murder is always wrong, and all abortions are always murder. In your mind, your beliefs are on the same level as being an abolitionist back when the majority opinion was pro-slavery.

Then, you extrapolate that up to the dozens or hundreds of different talking points that people will attack with the same kind of zeal, the talking points and political opinions that people use to literally define what "culture" they identify with and you have a significant portion of the country who not only aren't phased by elected officials saying things like this, but actively want to tear down the concept of majority rule, and actively seek the destruction of democracy and representation.

The truth, unfortunately, I think is far scarier and more disturbing than a lot of us would prefer it to be--we can't simply educate people out of not supporting monsters, because the monsters under the bed are genuinely the ones they want in charge.
