That's kind of fair, but there are a lot of people who have the acronyms BLM and ACAB in their handles.
ACAB is something that, until recently, was the kind of thing you'd see tattooed on the knuckles of thugs, like people who've been to prison for violent crimes. It's a little surprising to see it hijacked by the left.
You might be right though, I'm looking at a relatively small sample size that distorts the true numbers.
