I guess that's the question. Here's a mental exercise (DISCLAIMER: I'm not a white supremacist or a Nazi or anything; it's just that groups of nice people don't have controversial symbols

I think we can agree that someone actually modeling and scripting a cross burning on their property would be considered hateful content.
What about a picture of a burning cross?
What about a picture of a burning cross in the context of a news article, or a film poster?
I also agree that posting a massive swastika would be considered hateful.
What about a picture of a swastika in the context of an Allied propaganda poster?
What about the von Rosen cross (a similar looking figure used by the Finnish air force which is idealogically completely unrelated to the swastika)? (some Finns on the WWIIOL forums have made issue of this)
There's debates raging in Congress today on what is considered hateful and what is considered free speech. Sooner or later, this same debate will come here.
I'm not one to push it. I'm no Nazi, and I don't feel strongly about it. Like I said, I'm manually editing swastikas out of posters I put on my walls.
However, this will become an issue, because there are extremists, regretfully so, who will push it. I guarantee it.
