With all the talk of people doing Nazi salutes it seemed like you could open any news story about the counter-protests and you'd see clear evidence of Neo-Nazis but it was anything but, even when people point to videos [0] that are supposed to demonstrate the Nazi salute it's a struggle to even figure out who is supposed to be doing it. Another video [1] of that same scene is even less supportive of the claim of Nazi salutes. The discussion on such videos at the time always devolved into bickering about how strict the salute had to be before it counts on videos that were overwhelmingly of people with one or both arms in the air, closed fist salutes, people literally pointing, stills out of context, etc, on videos that were always accompanied by football chanting. I don't think I saw a single example of a strict or even semi-strict Nazi salute from a couple of days of casually looking up the news on the counter-protests despite every thread having a dozen people that were quick to point out that the protestors were racists doing the Nazi salute.
As far as the EDL / Britain First goes, this is literally the first time I'm hearing that the leader of Britain First showed up, it seems like it was drowned out of the news completely. Are there any pictures of said flags or the scale of their involvement? I don't recall seeing any at the time and I can't find any pics at all. Edit: Found one [2], it's of the leader.
