This exactly. Nazis will always exist, and there needs to be a sustainable and ethical solution to combatting that. Rehabilitation is that answer when they do not pose a serious threat. Violence is that answer when they do pose a serious threat. The dilemma is also on an individual basis.

I used to work at a houseless shelter. When I worked there, there was a neo-nazi who was accepted into our services. Whether I liked it or not, I was in a position where I needed to help this person. He was not an immediate threat, although he occasionally tested that boundary. He was an example of a neo-nazi who needed rehabilitation.

Meanwhile I was once at a Palestine protest where a neo nazi tried to join us. We told him to fuck off and he refused to leave. So he got punched in the face.

The answer to the nazi question is relative to the time, place, and other context. In a society like ours where neo-nazis hold power, violence is necessary against those that uphold it. In an anarchist society with a handful of neo-nazis who arent actively physically harming people need to be dealt with through rehab.

But also slogans, mottos, memes, and such dont really have room for nuance so... its okay to punch nazis!
