Turek winning would show that there’s no strategic downside to his politics in Iowa, or if I’m being really generous, in races to replace incumbent Republicans.
Great point. And the only way they can really know for sure if it'll work in other states is to test the waters there. And when they test the waters, you will completely capitulate for the exact same reason you want to capitulate here, and that's when it'll go from weak evidence that it works in other states, to strong evidence. So long as they never encounter any resistance, they'll keep pushing, keep seeing it work, and it'll keep spreading. It has to be nipped in the bud, above all else. If we wait, we won't be able to stop it at all.
That's how we got here in the first place. Because, they know they can fuck the left as hard and as frequently as they like, they know that they don't have to give you anything at all, because you won't ever stand up to them.
Obviously, words are useless in convincing people like you, because you fundamentally just don't have a spine. You'll happily sell out marginalized people because the Dems can just point to a boogeyman and you do whatever they tell you. The only real solution is to build solidarity between all marginalized people, which requires completely and unequivocally rejecting attempts to divide us with shitlib candidates like Turek. But you'll never do that, because you are fundamentally a coward.
