I apologize in advance for the commentary expressed in the following videos and article, I ignore it as much as possible and try to stick to basic facts about what I see. Some serious propaganda warfare going on. What do you think?
The following article has a picture claimed to be of, well, I'll just blockquote the caption:
A group of well-known Austin area fascists and neo-nazis arrive to support the June 10 anti-Muslim ‘March Against Sharia’ at the Texas Capitol, including a man in a LGBT For Trump shirt and rainbox cape, a woman in a Ku Klux Klan-like white sheet and MAGA hat, and a man holding a Thin Blue Line flag in a 1488 (neonazi slogan) helmet).

Here is a video from that "anti-Sharia Law" event showing the individuals mentioned in the above pic caption, but the obnoxious commentators have a different take, proposing that the group mentioned in the above pic caption are Antifa agent provocateurs.
June 10th, 2017, Austin TX, the rally against shariah - was the 1488 guy a false flag planted by Antifa?
The "well-known Austin area fascist and neo-nazis" certainly don't come off as RW in the video, and hardly so in the picture used on the supposed Antifia site.
I found a similar accusation in video of the Battle for Berkeley:
Antifa False Flags Caught & Media Proud Boy Anthropology
Reuters used a picture of one of the guys doing a Nazi salute [pic#6] with the following caption:

That shield, covered tightly with with black plastic revealing the three-skateboard shape can be seen being wielded by an Antifa attacking the RW side in video and other pics of the melee too. There are clear vids/pics too. At the time it just made me scratch my head, and wasn't bookmark worthy. Apparently they were covering Nazi-influenced emblems or whatever. I'll look for them again and try to post examples here. Are they Nazis undercover as Antifa or Alt-Right who afterwards remove the plastic to rejoin their own groups? Antifa who later remove the plastic to infiltrate the ant-Right side? Some other person or group, participating for who knows why?
Update: I found another example of black-plastic covered shields wielded by Antifa. They were used at the February 2017 Berkeley Milo event that was canceled due to Antifa violently attacking people & property. One example is around video marker 1:30 in the video at the following KTVU News site about that Milo event being shut down; This was previous to reports of serious injuries coming in later:
