I'm going to have to criticize the video on a few things. I don't think its ideas should be rejected out of hand, and it's an interesting watch, but let's not simply take it at face value.
And just for the sake of convenience, I'll give timestamps.
3:03 OK, there are two things wrong here. Right-wingers aggressively disagree with one another all the time. There's even
an entire Wikipedia article about the disputes between neocons and paleocons, including some pretty vicious mudslinging e.g. Pat Buchanan characterizing neocons as warmongering imperialists and David Frum calling paleocons bigoted, unpatriotic subversives. It also expresses a false dichotomy, saying that "Engelbert" making a "Charlemagne" argument or vice versa somehow proves they're insincere about their beliefs. But that's not how it works. People can sincerely hold ideas that seem contradictory to their overall political persuasion, but that doesn't mean they don't sincerely believe what they say. For an example, Jon Stewart has admitted to holding some conservative views. You don't have to adhere to an ideology 100% to be sincere about believing it. So his accusations about lack of candor fall flat.
6:02 And here we have the "is a dogwhistle for the Jews" argument. Not "can be", is. Which implies that nobody can criticize certain things without being an anti-Semite. I think he might be joking here, but I haven't seen the rest of his videos, so I don't know for sure. To flip things a little, there are right-wingers who say that any criticism of Israel is a dog-whistle for anti-Semitism. Yeah, some is, but not all of it. Plenty of Israel's critics don't have anything against the Jews, and are just genuinely opposed to, say, its settlements in the West Bank. The same goes for people criticizing postmodernism, globalism, or George Soros. Sometimes a cigar is just a cigar.
13:18 Let's not pretend feminists never physically attack people who upset them. Andy Warhol got shot by a feminist over a misunderstanding. I could point to plenty of incidents where one or more leftists have gotten violent. Now, I'll agree that a Nazi is probably more likely to stab you, but let's not pretend offending leftists is automatically "safe".
13:30 There are a few things I disagree with around this timestamp, but I don't think most of them are necessarily flaws with the video. Maybe I could have a friendly discussion with him about them, if he deigns to respond to my (hypothetical) comment. But the bit about "conservative rhetoric" seems to indicate that he's conflating "conservative" with "alt-right", when there are quite a few conservatives who hate the alt-right, and the alt-right is known for being very critical of more mainstream right-wingers. Or maybe I'm just being an idiot and not getting something.
17:10 /leftypol/ has left the chat.
Now, to clarify, I don't hate this video, and I think it makes some interesting points. Hell, since I haven't seen any of this guy's other videos, maybe there's some context I'm not getting. These are just some thoughts I have about the video. And I'd be happy to discuss them with you.
