I've watched it and it's obvious that you intended to be provocative and I think you managed, without going over the top. Content-wise, the Marxist analysis is completely wrong, as it's been proven time and time again through history, that much is true. That said, I would never censor your talk for being provocative and wrong.

Let me add though that I would also be OK with a talk titled "Satoshi was a true Aryan National-socialist warrior" that tried to sell to the audience how Bitcoin is about bringing down the Global Jew, or some other such complete nonsense.

Yeah, that's where my bar is as far as free speech is concerned. Well, my point is that I don't think I have one, I'm a free speech absolutist.

Going back to your specific case, it's likely that being in a Baltic country, the organizers have a much lower tolerance threshold towards (perceived?) pro-communist speech.

Again, if I put myself in their Baltic victim of communism shoes, I would still not censor your talk, but I would probably have had a counter-talk immediately after, even if I had to improvise it, or I would have asked you to not give the talk and invited you to a debate instead.

Silly and wrong views should not be suppressed but exposed and countered in public with arguments.
