Don't think you do buddy! Do you think you can sue a shop owner if they throw you out because you're saying things they don't like?
If you know so much about the first amendment and it doesn't apply to Internet forums and platforms, how come you're not rich from suing Twitter or something?
The shopping mall is not legally obligated to eject the Nazi.
But, you think government should force action upon the private entity because the majority disagrees with Nazis.
That's exactly the opposite of why the 1st Amendment exists. Everyone else learned this when they studied why someone can burn the flag or why the ACLU supports Satanists.
I've no want for your nonsense. And, you do a disservice to others by repeating it. Go learn about quasi public spaces.
