Actually, they're just another brand of violent communists. Probably dirtbags paid by Soros.
From what I saw most of them were real people who carried anti Trump signs but didn’t soeak although my son overheard one couple saying that Trump was Hitler under their breath.
But there were a few SEIU signs here and there. But the main group of protestors seemed to have been somewhat corralled off, at least from the entry/exit area to the protest and they were overwhelmingly surrounded by riot gear clad cops so I didn’t see them..
On our way out there was an aggressive group of maybe 3 or 4 who waved a huge Mexican flag whilst yelling F Trump.
Didn’t see the fight where the Trump supporter get bloodied so no comment on that yet.
