He really isn't. First panel? Sure. Second panel? Sure (though it is funny that "Rodeo" is apparently a white guy thing. Vaqueros must be spinning in their grave.).

Third panel? No, that is where it gets dumb. Having a couple of white protagonist isn't "celebrating whiteness". It is having a couple of white protagonist. It is not a weird thing in a white majority nation, especially given the source material is based off of Norse Mythology for one of the examples and WWII propaganda for the second. I just came back from watching Infinity Wars, and it isn't some kind of snowfield or Nazi Whitepower celebration. If anything it was pretty diverse.

Fourth panel is also stupid. How is "whiteness celebrated" in the leadership? Did Obama take part on secret KKK parties with that polite angry look on his face? What is that even supposed to mean?

Last one, sure. The second to last one really has to make up its mind on if they are overly privileged middle class or the poor white trash verity of neo-nazis. In either case making sweeping generalizations of your opponents really won't help you understand the issue and make informed actions.
