I agree the defined “group” is more or less non existent. Again, back to the individual. I’d put BLM supporters in the same genre as Trump supporters. So you’re right in saying it’s bullshit to call “black lives matter” violent. So that woman who violently shoved the other isn’t necessarily “black lives matter” incarnate. She is an individual that supports the BLM movement, at a BLM demonstration, that acted violently
antifa is more defined, and would be more comparable to a specific group like the proud boys
