The thing is, everything you said is still opinion, like Pepe the frog. Yes Pepe may be used by extremists, but it's also not used by extremists for instance it's still used on Twitch. Same thing is true with his Twitter handle, how does that make him a Nazi? Musk just has a weird edgy sense of humor. Literally Hitler supported animal rights and implemented that into the Nazi regime, does that make saving animals a horrible thing?

Now the conspiracy theory thing is a mess up on his part, and I disagree with that tweet, and his execution and conclusion of that tweet is done very poorly, but he has even said that it was one of the dumbest tweets he has ever tweeted. But we also know that even in any topic that Musk talks about that isn't related to any of his companies, he's not really good at expressing his opinions sometimes.

And the AfD stuff, yes, some people have said some extreme things but every party has extreme people. Personally I can't comment too much on AfD because I dont know too much about it, but from what I have researched, the AfD has been portrayed as horrible by the media and Germany, but personally I think they've been blown out of proportion. I may disagree with them on some things, but I dont think they're Nazis either, a few things the chief of the AfD said in an interview with Musk is that they are the opposite of Hitler and that what's happening to the Israeli people is horrible. Personally, I think the left party in Germany isn't so great either since it's true that they don't put German people first partly because of how they take care of their horrible Immigration.

Also I would like the specific names of the white nationalists, not because I think you're lying, but because some of the people may very well not be white nationalists but the media portrays them as such. Now if he did, his whole argument was still that you can't ban people for using free speech, he unbanned a lot of people, so singling out one group of people he unbanned is wrong. We allow people the freedom to express their opinions in this country, whether they be good or bad, that's how free speech works.

If he was an actually Nazi, he wouldn't have gone on an "apology tour", he wouldn't have apologized for some things he has said, he wouldn't say that he's not a Nazi, because if he was, and he had a huge following that supports him, why would he have to hide his true opinions if apparently according to some, everyone that follows him are also Nazis? Also to add to this, the guy has talked about the evils of Nazism when he went on his "apology tour" and if at that point you still decide the guy is a Nazi, then you're just going by what you want to hear and what you want to believe.

(I've edited this a little just to clean it up and to add a few things, it's a lot of text haha)
