I don't expect that Antifa is really going to much to the Nazi's here tbh. They certainly do not have the political power to do much of anything at all to anyone really. They just exist because they really just want to stomp Nazis. I mean that isn't that uncommon a sentiment, but still, they do not have any actual " power" to do anything at all really. They are more of a symptom of the larger problem of people feeling powerless to be able to stop them or feeling like they are just sitting there doing nothing while knowing this is getting so much worse.
You are also IDF in Israel. It is also not just about the Jewish people, it is about all minorities in the US. You are a soldier in a 80%+ Jewish nation, you can defend yourself, for now. Not everyone here can do the same.
An arson at a Needham synagogue and vandalism at a Fall River cemetery contributed to a record high number of anti-semitic incidents in the U.S last year.

People are being harmed here, people are afraid here. We are seeing these things happening in our communities. Then, when all of our intelligence agencies telling us the same thing, that the biggest problem we have right now is these far right groups growing and gaining political power and have infiltrated US military, police and all levels of government, we would have to be idiots to ignore it. It is no longer just " oh look at the idiots who killed the cow and carved a swastika in it and left it on their driveway" anymore, it is people being elected to offices, being put into positions of authority to where they can kill people and impact their lives, where they can have control over others and inflict actual harm that this is a growing concern here. Not doing anything at all about it though leads to so much worse, so we have to have solutions here somehow.
(EDIT: The whole weird cow thing actually happened to a Jewish family living down the street from my parents farm growing up, just in case you didn't understand the reference) This town here has a long history of racism and protecting actual Nazis and providing them a place to flee after WW2. One my parents immediate next door neighbor was literally SS, with photos of him in his SS uniform on his fireplace mantel. He is dead now, but the local Neo Nazis treated him like a celebrity, and his son shares his beliefs, so this didn't die with him.
