> Leftists aren't actually oppressing anybody.
Well, that's certainly not true. They are absolutely oppressing people. They may be oppressing people that you or even I think ought be oppressed, but that doesn't mean they're not doing it.
> We're still under the rule of the far-right in the US (a country which does not actually have a left wing by Western standards).
That's true around economic issues. It's not so true around identity politics. The political climate around those issues in the US is very much left of center.
> Voting with your dollar and pointing out bigotry and inequality is not oppression.
That kind of depends on what exactly you mean by that. Naming and shaming individuals for social transgressions based on hearsay seems pretty oppressive to me.
