The thread title is off topic, that's the only rule you're breaking but I'm sure the mods don't care.
As for the case, this is a more criminal issue isn't it. Surely in the USA rules exists against inciting hatred and violence against a groups. If so this would be breaking the law and as far as I know it is illegal to make money from a crime.
I dunno, I know nothing about 'USA law, perhaps someone here knows a bit more.
