Is this the libertarian "taxes are theft" meme?
No, it's a simple statement of fact. Using force to steal from people is robbery. A smarmy attitude is so much less effective than logic.
I've never known progressives to be unwilling to acknowledge the fact that public services and infrastructure are funded by taxes.
That's an unsophisticated straw-man. Nobody suggested those services aren't paid by taxes. We could have a conversation about which taxes are more or less coercive or moral and what services need cutting, but you've already shown you're nothing but an insulting Communista looking to score points and not worthy of being taken seriously.
the contention from progressives is that the harm of hate speech outweighs the value of allowing it.
The fist/nose analogy is solid when the harm is direct, physical, and provable.
But “hate speech” isn’t a punch. It’s a category that keeps expanding until it swallows any opinion that makes someone feel unsafe in their ideology. Today it’s slurs; tomorrow it’s “misgendering”; next week it’s “climate denial” or “criticizing open borders.” The progressives’ harm argument is almost always subjective emotional distress, not measurable injury. That’s the sleight-of-hand.
it's not like Republicans are better than Democrats on this issue.
You've obviously noticed I'm Libertarian. So, I'm not interested in either of your partisan apologist takes on censorship. Both are simply wrong.
If your claim is that Joe Biden is far left, then you have a fundamental misunderstanding of progressive politics.
My claim is that people like you have a very high likelihood of wanting to put people like me into a concentration camp. Additionally, Wikipedia is biased and I'd argue more than Rasmussen (which your Wikipedia link shows as "having an average error of 5.8 points and a pro-Republican bias of 3.9 points"). When 45% of a group says they want you in a concentration camp, it's best to pay attention despite things like your weak denial. Gulags and Communists go together like peas and carrots.
