It may seem unfair that the left would have to put so much effort into communicating with the right, who doesn’t give a fuck.

It’s about, nay, exactly the same reason why therapy is harder than causing trauma. The good news is that not causing trauma is not as hard as fixing it so it’ll get easier over the generations, the important bit is to find ways to effectively chip away at things.

Looking at the US, and thinking a bit out of the box: Start by de-normalising hitting kids, and don’t shy away from “if you don’t, then they’ll be able to get better jobs” type of arguments. You might think “but but am I not advocating for individualist turbo capitalism like that” – not really. Or at least not in the long term: To make anyone listen you have to simultaneously teach parents how to deal with the little shits in a non-hierarchical way, thus also teaching the kids that that’s possible, making them more prone to act like that once they’re adults. The “think of your kid’s career” part is just the hook, the rest is prefiguring Anarchy. Baby steps but hey you gotta start somewhere.
