Leftists: why associate yourselves with an ideology that will attack you at any moment for not being "woke enough"?

Then on them for what? And what makes you think conservatives don't do the same thing?

Turn on them for unorthodoxy, when someone fails to submit 100% to leftist dogma without a hint of disagreement or free thought. Conservatives occasionally do the same: I don't think it's right to gatekeep either way.
