We tolerate people that hold those beliefs in that they are allowed to exist in open society where they can be called out

This point is hugely important, but not for the reason that you intended.

You are mistaken on an essential aspect of your argument: calling out bigoted or discriminatory views out is the definition of not tolerating them. At the same time, the bigotry you’re describing - not permitting people to exist in open society - is exactly the reason we cannot tolerate those kind of views.

The essence of bigotry is that entire categories of individuals don’t deserve the same rights as others. People who hold those views aren’t interested in debating the issue because they believe that their opponents don’t deserve the right to be part of the discussion.

One side is saying that we cannot tolerate these views. The other side is saying that they will not tolerate our humanity.

This isn’t a perspective that is subject to change by reason.

Lol, nope. You actually have it entirely backward.

Nazis can never win arguments. They can’t. Their ideology is not based on reality. It’s not based on material conditions. It’s not based on convincing others to join them with hard data or well reasoned positions. Nazis win people over by talking to them. They win people over because people who are privileged are opposed to any recognition of that, and above else want to continue to be privileged.

You will never lose a rational debate with a Nazi. It’s not really possible, because the nazi will never make rational arguments with you. Nazis instead will allude to conspiracies. They will allude to secret shadow societies that control everyone and that have the explicit goal of upending class hierarchy to take away privilege. Pay attention next time you see a Nazi argue something. See the language they use and see the way they position reality. Nazis lose rational debates. So they never have them to begin with.

Nazis will instead reach for the nearest loudest microphone and will scream their bigotry as loud as possible. They print newspapers, they do interviews, they famously were highly intertwined with radio networks, and so on. The method by which their ideology spreads is by subversion. It’s by creating fear of a secret other controlling everyone. The sad fact of the reality is that you cannot argue against that subversion. The argument isn’t rational to begin with, rationality cannot disprove it in the minds of those who believe it. A core part of the conspiracies are actually that anyone who argues against them is a part of the conspiracy. Any opposition to Nazism comes from those secret shadow society elements, and so any argument against it can be immediately dismissed.

Simply put, no. The marketplace of ideas is actually perfect for Nazis. If Nazis can’t create mass subversive fear of minorities then they cannot recruit. The KKK has largely been expelled from society for the past century (not entirely). You’d think that in a hundred years if, recruiting from the shadows was better for them, membership would be most of the country. Say what you will about American fascism the average voter definitely doesn’t think positively about the KKK.

Speaking with a Nazi posits that their ideology has the same value as yours. By engaging in a debate with a Nazi, which they won’t win but will instead use the opportunity to further spread Nazi ideology, you legitimate Nazism as a valid position to take. Now someone can be a Nazi, it’s okay to be one you can be a Nazi and still deserve the respect of an audience.

Nazis should be expelled from society in their entirety. Neoliberal propaganda has convinced you that all ideas have value. They do not. Killing minorities is inherently wrong. Spreading ideology that advocates the genocide of minorities is inherently wrong. Nazis should be met with a fist. Their media should be dismantled, and they should be imprisoned or expelled from society. Time and time again we arrive at this same place. When I wonder will anyone actually learn?

You’re wrong, and all you have to do to realise it is look around (hint: when you allow bigotry to exist in open society, aka, tolerate it, it will keep growing like the fucking cancer that it is).
