OP here, just got back after chequeing the thing out. I took a lot of video and few pictures, but here's a few I took. The turnout wasn't bad considering the 95 degree heat. Both sides were pretty vocal and organized, but unsurprisingly, the anti-confederate side was riddled with wound up, cussing, nasty people while the pro-confederate side remained collected. Never heard a single gentleman utter a curse word.
Also there was this pro-sharia muslim that didn't belong to either side. She wound up getting in a screaming match with an anti. Quality entertainment.
