No, that's true, and as I said, I agree that if you're going to blame a person or a group of people, you'd better have some pretty serious evidence. Not so if you merely point at the toxic political climate as a likely contributing factor, though.

Of course this guy is incoherent, and of course he won't have reached such bizarre ideas as he has just by watching Fox News. But you seem to think that crazy conspiracy theory blogs are somehow entirely separate from the mainstream political space, and that they aren't influenced by mainstream political actors (be it politicians or partisan media sources). I think that's a rather odd assumption to make. The people writing crazy conspiracy blogs follow the news like the rest of us do, sometimes even more so, they just interpret it in bizarre ways.

To some extent, some people on the left are doing that, yes. But as I have said a number of times now and am growing rather tired of repeating, there is a big difference between using this as a partisan weapon, or using this as a wake-up call to the nation that the polarization is becoming an ever growing problem. The latter is perfectly valid, and I would even say rather necessary.
