The way I see it, it's more like they're ok with it as long as the knife is pointed at someone else. Fascism is imperialism brought home. All that imperialism has been happening non-stop and even at home, marginalized groups have been subject to all sorts of terrible things.
They'll call that less bad because it doesn't affect them yet. And in the narrowest sense I guess they are technically correct exactly in the short term. But 1) It's not better for those other people. 2) They don't see how one inevitably leads to the other. The same tools they built to stop "our enemies abroad" can and are used to suppress dissent at home.
If a Dem ran that as a fucking bare minimum promised to reign in the military, police, and surveillance states and curb executive power, I'd be more sympathetic to the argument for harm reduction even if they didn't agree with me on other things. But if they're just going to keep enabling all of this, at best the only "harm reduction" happening is some people getting to ignore the suffering until next election.
