If it had been the other way around and some white guy was being called a “Nazi child rapist”, I’d expect them to get away with it in pretty much any western country. It’s true that his behavior was illegal, but the reason he was prosecuted was ultimately the content of his speech in my opinion. There have been other right wing figures who’s names I don’t recall who were also recently convicted, and they weren’t speaking in a court room at all. Other anecdotes mentioned above were French pro-Palestine activists.

You’re right that Robinson was in the wrong on this one and that he did commit a crime; I wouldn’t have used him as an example had he not been brought up specifically.

Even in the U.S., there are people actively lobbying to use the government, usually state governments, to restrict the BDS movement. In my opinion there’s been a lot of media attention around silencing right wing speech in order to get the left to comply in undermining the underlying legal principles. But at the same time, quieter work is being done to restrict left wing speech as well. This has already been put in place in Europe and there seems to be bipartisan support for it in the U.S.
