This is a video he posted, and still has up to this day, as you can see, where he dressed as a dentist and talks about removing immigrants as if they were dental cavities.
Here’s how I see it: It’s a crime that he’s locked up, the Russian state is a criminal organization through and through, but calling for the extermination of immigrants is not something that normal people do.
Now to be fair, he hasn’t made any new comments in years, but neither does he respond to requests to take down the video of recant his statements contained within it. It’s a complex situation, but I don’t think he is a good person to rally behind as an alternative to Putin. Ultra-nationalism isn’t a good look on anyone.
