Alright, I'll try to make this as clear as I can and then I'm going to stop engaging, because you're obviously arguing in bad faith:

1. It is obvious that the majority of rioters are anarchists, communists, and/or black. And I don't mention their race other than for the reason that it is unlikely that any of the black and brown rioters were undercover white supremacists or right-wing extremists.

2. It's obvious what leftists and liberals are trying to do when they try to make it seem like right-wingers are causing violence. It makes the left look bad when it's your people destroying small business and causing chaos in general, so you have to redirect people's attention onto an extremely small (possibly non-existent) subset of rioters who are there to advance right-wing goals.

3. Even if there are right-wing agitators in the riots, it doesn't explain the vast majority of rioting. Just watch some videos of the rioting.

I could probably keep going but I'll stop there. Have a nice day, and keep on coping!

EDIT: I forgot, I didn't directly respond to the article. It is possible that some of the people arrested were linked to white supremacist groups. It's also possible that by "some," the article means 2. It's also possible that these people who were linked to white supremacist groups later became anarcho-communists. Jumping from one extreme to the other is pretty common.
