The stupid part is that the third-way labor parties and social democrats are doing a much better job at socialism

Well... no, not really. It's not that leftists hate social democrats... every anarchist I've ever spoken to appreciates the effort of people like Bernie and AOC - it's just that we understand what they are allowed to do and what they aren't. The political establishment will allow them to protect capitalism from itself by restraining it's most obscene aspects it to a certain extent (and even such meagre self-protective measures are a bridge to far for the right-wing hivemind)... but that is all they could ever achieve.

Remember - no matter what the media hysterically screeches - the term socialism has a very hard and uncompromising meaning... a condition wherein the workers control the means of production. If it doesn't measure up to that or only pretends to measure up to that, we can't call it socialism with a straight face.
