Meaning no slight to your character in general, in this conversation you are one of the extremists.

There are plenty of countries (large parts of Western Europe post-WWII) which have had predominantly left-leaning governments for 60+ years and not devolved into centrally-planned communist states. There's a genuine debate to be had about the role of governments, markets, taxation and distribution, but trying to frame it as the world threatened by the sword of communism hanging over all our heads just stakes out your position way out on one side and signals a refusal to enter any kind of debate.
