“extremism” is distance from the status quo, it doesn’t have inherent properties in terms of the outcome because it is a relative term.

What you are doing is employing the argument to moderation fallacy as if some golden middle point is always the correct answer. Communists and anarchists are the only people who care about my rights, liberals and centrist only care about me when it is time to virtue signal for votes and then do nothing for me. Being a centrist is the most selfish, ignorant and privileged position to take, you try to act like you don’t support the far-right but being a centrist and doing nothing only serves the current hierarchies in place which harm marginalized groups.
