A couple of those I would say it's probably good to avoid, like "rule of thumb" and "go off the reservation..." those are unambiguously linked to domestic violence and suppressing entire cultures. Others are a bit much.
However, the fact that you're posting this speaks volumes about your susceptibility... you're being played like a fiddle by the Republicans. They've got you worked up about CRT myths and language selection while they're busy screwing you over with anti-democratic legislation and overt corruption.
The "Rule of Thumb" thing is very unclear - it seems like it's a myth that became such a widespread myth that it might as well have been real. As far as I know there's never been any historical law that legalised domestic violence on that basis, but the myth became so widespread that it even got cited in legal contexts.
"Go off the reservation" seems pretty obviously dodgy, I can't see there's much room for doubt about that one.
Most of the rest, complaints about "violent language" in phrases likes "I could murder a bag of chips" or "knocked 'em dead" are nothing to do with 'the left' or 'political correctness', or 'social justice' they are complaints that are as likely to come from a conservative type as a leftist. Probably far more so. It's the same sort of thing as objecting to violent video games.
