Is this the part where someone points out to you that all your arguments also apply to rape and murder pictures and you handwave it away and the circle begins anew?

just removing one evil ideology and replacing it with another evil ideology you don’t have a problem with, it just laughable thinking at best

Filter existence, you realize that you know?

What kinds of things do you want to have people saying in your fandom and on your platform(s)?

Do you really want to welcome in people saying things that trivialize and glorify Nazism? Because, I could be mistaken here, but it looks like you want to welcome, or at least make excuses for, people who are trying to trivialize and glorify Nazism.

Implying that there’s no such thing as a reasonably widespread consensus on certain moral ideas like, “Hey, maybe genocide is wrong.”
There is.

1. Not having Nazi images on this platform isn’t “censorship.” That’s a red herring that gets thrown a lot by people who don’t understand what real censorship is. Nothing would stop you from creating Nazi images or whatever other expression you feel like, and nothing would stop you from posting it in whatever other venue will have it. Not letting you set up a soapbox on my front lawn so you can scream at people who pass by does not mean I’m “censoring” you.  
2. It’s a drawing contributing to trivializing, glorifying, and supporting an idea that there is a strong moral consensus is really shitty, and is profoundly offensive and hurtful to many people for very real and very good reasons. This is not just the empty “video games cause violence” argument. This is an actual thing that has hurt many real people in real ways, whether you choose to see it or not.

the days when you could counter bad ideas with your good ones, instead of just trying to silence anyone you didn’t like.

and the Atlantic article had absolutely nothing to do with it.
