“Western civilization” is a dogwhistle, and doesn’t actually represent the West, since that would mean supporting liberalism. AfD is an illiberal movement. The Nazis claimed to be socialists, too - reactionaries lie, what’s new?

EDIT:

In January 2022, after a lost power struggle, party leader Jörg Meuthen resigned his party chairmanship with immediate effect and left the AfD, as he claimed he came to acknowledge that the party had developed very far to the right with totalitarian traits and in large parts was no longer based on the liberal democratic basic order.[44][45] Former party chairman and co-founder of the AfD, Lucke, had left the party in 2015 with the same remark.

Some of the citations are in German, so if you don’t read German you might have to use Google Translate or another tool to confirm these things for yourself. Just wanted to provide some evidence for the claim that AfD is illiberal, since they claim to be an economically liberal, conservative movement.
