"Sean got fatter" sort of weird, and some have latched onto it as a kind of answer to white supremacy in general, like saying "This is genetic superiority? This?"
I think it seems bad especially because there's this weird bulge on the left. I note it mostly because it is roughly the same size and shape and placement where you'd expect a liver to be:
a great huge drunk. But that's massively unfair. Lots of people have bad skin and lots of people have drinking issues--I drink, myself, rather more than I would always like at times. And this does not make someone "bad people"--you can be fat and have bad skin and even drink a shitload, and that doesn't make you a bad person. I am a little fat and drink a bit and am not a Nazi. But it is very probable that Bannon is, in fact, an actual bad person based on his personal history and editorial output.
In short, you just don't know from a picture what a person is about, even a grossly unflattering one. You should judge them based on what they do.
And for all we know, he might just have an alien in his guts.
