Unless of course you think that population is totally logically in their views?

No, they aren't. The extreme left is almost as bad as the extreme right. I suspect that's where the anarchists reside. Defund the police, open borders. Near that group would be totalitarians (both extremes have those).

There are also a few anti-vaxxers among the liberals who clearly don't use logic or science. The right has far more anti-vaxxers than the left does, but the left has some.

However, most liberals are not extreme. They accept science, they expect the Constitution and other laws (and due process) to be obeyed (and will throw one of their own in prison if he/she doesn't), they generally don't believe in discrimination, and so forth.

If you think that I think "extreme liberals" are without flaw, you're not paying attention (to this board, at least). "Extreme" anything is almost always bad.
