It ws probably targeting liberal protesters, so this may be a Leopards Ate My Face situation.

Oh yeah the hate speech is legal, it's just the hanging of the sign on public property that isn't.

In America being a Nazi, or anti-semitic IS legal. However excercising your free speech in any way you want, wherever you want, isn't legal unconditionally in any state, not just your ignorant Florida stereotype.

To be fair, I lived in Florida from 1980 to 2007, they loved Florida then too.

That's nothing. We had an actual Nazi in the Canadian Parliament and gave him a standing ovation!
