Because they try to maintain a veneer of rationality in everything they do, while trying to paint everyone else left of them as kooky

Much better than mine for sure. Which program are you using?
paint.net, but i spent longer on it than i probably should have
Fair enough, I spent 5 minutes on it in GIMP.
"I'm totally not a conservative you guys. How dare you suggest such a thing? The fact that I loudly virtue signal about idpol, 'pragmatic solutions' and other buzzwords means you're not allowed to evaluate my actions."
No. You're still thinking of them as separate when you need to think of them as a single thing with two parts. One doesn't work without the other. It's like a ball and socket joint or something. Either on its own doesn't get anything like the result of having both parts functioning as a whole. Replace either party with something else and you lose the emergent property.
Republicans don't try to masquerade as lefties, so they aren't as much of a threat to us.
The Liberal Democrats are especially vile, because ever since Labour replaced them (as the Liberal party) as one of the two most powerful parties, they have only existed as a tool for the Tories, actively trying to split the Labour vote because they'd rather have the Tories in power.
