Not to be a pedant, but "SWC /pol/ edition" is pretty damn redundant.
Anyways, it's hard to avoid political discussions if you're covering comics that are political in nature. And as far as I know, all the well-known right leaning bad webcomics have already been done, whereas left leaning bad webcomics are now in vogue with all sorts of artists. That tends to skew the discussion a bit, though I will admit that people's personal leanings are still a factor. At the very least, I like to think that those of us who already know each other can have an engaged discussion rather than the shitflinging you see on /pol/.
If you don't want to take part in the discussion, that's fine, but if you find yourself wanting to leave, not because there's any sort of political discussion, but because you find more voices disagreeing with you than you're comfortable with, then maybe you'll want to consider if it's because you're too insecure to argue your own viewpoint? Because nobody here's going to stop you. If you make a claim, people are going to scrutinize it, and you can scrutinize their claims in turn. Nobody here really cares about winning or losing arguments so much as trying to dissect good and bad arguments.
