A dog is being trained to raise its paw in a certain way. I'd say that's mocking Nazi's and their overly authoritarian regime and conformity towards it.
1: RationalWiki is a joke. I've seen less bias on Uncyclopedia and Encyclopedia Dramatica combined, and they're at least self-aware that they're satire.If Alex Jones isn't seen as alt-right, then why do many people in the alt-right know and like his work? RationalWiki has also categorized Alex Jones as being a part of the alt-right and he himself has had contact with several alt-right personalities over the years. Tommy Robinson may not be as popular a name, but nationalism is a trait most people in the alt-right tend to have.
2: Many of the actual alt-right (white supremacists who seek an ethnostate) only like Alex Jones ironically because of his stupidity; otherwise, they consider him a shill.
3: Contact with the alt-right does not an alt-right make.
4: Being a nationalist /=/ being alt-right.
Let's not tangent too much onto history. Nobody is talking about Hitler in a positive manner here.It's like I said before. People do not take fondly about talking to Hitler in a positive manner because he represents a dark time for Germany and the world in general. He's one of the main reasons World War II got started and it's likely he would've taken over all of Europe had the United States not been invaded by Japan or declared war.
Are people free to tell him that his joke is not funny, and for them to think he's potentially a neo-nazi? Sure, that's free speech in of itself. But there's a clear difference between subjective opinion, and being punished by the law of the United Kingdom. This is clearly the latter.And again, I do have some sympathy for him. But since people do not like others talking about one of the most reviled figures in history in a positive manner or even like neo-nazis in generals, Dankula is going to face consequences. It isn't an assault of free speech, it isn't a sign of it dying out either. It's simply a case of someone making a really bad decision in life and now he's going to have to deal with it.
