I don't buy the bullshit about him regretting the tattoos. That swastika is tiny, it would be easy to tattoo something over it. The text on his back can't be removed as easily of course, but it wouldn't be nearly as bad without the Nazi flag.
About White Pride vs Black or Brown Pride, yes at a first glance it seems hypocritical to say that they are different, but when I think about it, I can see that there's a difference between a minority or a majority in that sense.
For a minority, "pride" can be seen just as refusing to consider yourself inferior to the majority. But if you express pride in belonging to a majority, it's not really pride in yourself, (because most people around you are just the same), but rather contempt for the few people who don't fit into the norm.
So the smaller the minority of people you are proud not to belong to, the more threatening it will appear to them, and the more fascistic your opinions will appear to a third party. And in Finland you literally have to walk inside an ethnic food restaurant to find someone who is not white, at least outside of the capital.
