How so? Leftist censorship became quite popular on college campuses. The ACLU supported that, and got cold feet about promoting free expression more generally when it involves organizations or causes it doesn't like.

I'm a lefty, but I absolutely believe that both the left and right are deep in the "ends justify the means" weeds with respect to censorship and free expression. I blame partisanship. People used to have respect for someone taking a principled stand that didn't necessarily align with their overall political position. Now, that's just seen as a weak maneuver in the all-important "my team vs your team" culture war.

> The whole conservative project is doomed from the start as it has to confront science and progress like the emancipation by women, lgbt people and certain ethnicities.

I have no idea what you're talking about. There is no scientific or natural law that says that every human should have equal rights. You can totally make a stable society that discriminates on color of skin or possession of certain documents or account balance. It's been done many times. Science does not tell you whether votes should be extended all the way to ducks but not chickens, nor whether unauthorized presence in a country should enable arbitrary search and seizure. Plus, "conservative" covers a lot of ground and someone can legitimately be extremely conservative and completely opposed to (eg) white nationalism at the same time.

Sure, conservatism is always going to drag its heels to recognize and accommodate the sorts of progress in science and other understanding that I'm guessing you're thinking of, but progressives can just as easily go too far too fast and be blind to the tradeoffs and principles involved. The "conservative project" can't be doomed; it will always be a different point on a continuum from the "progressive project", and we'll always be able to argue over where the right point is.

Well, at least until we're all dead or so infantilized by our technology that we stop even asking the questions.
