I don't know how well BLM is organized, but I've come to believe Antifa is hardly more than some kind of collective consciousness which tries to root out elements of fascism wherever they see it. As far as I know they have no effective real leader, and no effective real organization.
On the other hand, it appears to me to be a semi-effective red herring talking point for many on the right side of the spectrum. It seems they're taking their cues from Trump, the foremost purveyor of the evils of Antifa. Evils that supposedly far outweigh anything his right wing militia and white nationalist followers do, including storming the nation's Capitol. A classic red herring.
No, I just don't want to waste my time.
@FGG has already made a number of credible rebuttals to those videos, but I don't recall you making counterpoints to her points. Did I miss something where you actually did reply? -- I really had thought I might take a look at them, but FGG essentially confirmed for me what I felt I already knew. -- You may call it stubbornness; I called it using discernment.
