Your second point contradicted your first one.
To answer your first point, how is an unarmed female dangerous? Also, in what world is getting shot in the neck for trespassing an equivalent consequence for that action?
To answer your second point, Floyd had overdosed Fentanyl, an illegal and harmful drug with a known side effect of trouble breathing. That, on top of his COVID-19 breathing problems, have been proven by autopsies to have been his cause of death. Granted, holding his knee on his neck wasn't the best way to approach the situation as he had backup, but the knee on the neck is in fact police protocol.
Now with that out of they way, I can explain to you the purpose of the meme. This isn't saying that the preceding events are ok, it's just to make everyone aware that this isn't being talked about nearly as much as George Floyd was and still is. That makes the media racist towards caucasian homo sapiens, no?
