I'll remember you wrote this the next time someone that is right leaning does anything remotely like this in the future.
If you want to make the argument that this guy heard some left wing commentator and decided to act on that commentator's ridiculous notions, I'd be more than happy to listen.
That said, this guy's overall philosophy seems unrelated to either political party, or even their most radical cheerleaders. His apparent motivation had nothing to do with his anti-immigrant views or his more mainstream environmental views, but instead his completely nutjob idea that we should all just go die in a hole somewhere so we stop screwing up the Earth. That's not really something that falls within the political spectrum.
