I’ve never seen someone on Reddit or in real life suggest that capitalism is good or that freedom of speech should protect nazism hate speech.

Are you an American? I live in a post-communist country and most of my knowledge of the US comes from various media (traditional and social, new and old), but if you are, I honestly find this fascinating, considering that free speech is even in the US constitution.

We do have laws against specifically promoting nazism, so that doesn't really apply to me, but I'd say that about 3/4 of people here consider capitalism to be if not good than acceptable.
