I think he's posing as a Q anon guy, but is actually antifa. One thing Q is always known to be against is child trafficking and pedo stuff, and one thing they always look for/bring up is symbolism. That viking guy had a very strange tattoo on his chest that was clearly visible, which is almost a perfect match for one of the pedo symbols on that FBI wikileaks document a while back. Someone who's into Q would never get a tattoo of that sort, and instead would point out someone as a likely pedo if they had that tattoo.
