Your argument is to say they are incorrigeable and there’s no point in talking to them and the only thing we can do is to shove the problem under the carpet.

That also sums up my position.

If you do that, the problem will only accumulate.

First of all, I don’t think that’s true. If we ban advertisments for Coca Cola, we just push the problem under the carpet, and Coke fans will only accumulate?

That, of course, is nonsense. When everyone else is allowed to do normal marketing, while you are not, your product, idea, or ideology will slowly start to fade, fizzle, and die out. I mean, if what you are saying is true… Do the Nazis also think so? Do they understand your argument? Do they think that their groups, their views, and their representatives should remain banned? After all, your argument goes, this is what will make them “accumulate”.

For some reason the Nazis themselves don’t seem to want that. They want to be on national television. Literal Nazis want antisemitism on all channels, and holocaust denial taught in schools. They apparently don’t understand your argument, that ideologies accumulate and win, when you suppress them.

I suspect that Nazis are correct when they themselves reject your line of reasoning.
