Do you think it's wrong for people to go around waving confederate flags?

There's a huge one near my neighborhood, just off the freeway in central Florida. You can see it for miles. I think it's absolutely disgusting that we allow a symbol of treason and secession to be proudly displayed in public, as if it's something to be admired. What if a group of German nationalists advocated for the right to put a Nazi swastika flag outside somewhere in public? Would you support their "right" to do that, in the name of German pride?
