I've heard this argument before. In the 60's. When I saw that video I was so angry, it would have felt good to see Amy Cooper lynched (figuratively).
I was too young to be directly involved in the civil rights movement, but old enough to be a witness. When I saw the dogs and fire hoses, Malcom X was much more appealing that MLK. As an adolescent, I wanted a physical fight. I though that's the way to win. Punish those racists to the max.
Now that I am older and I've seen a lot of battles, I understand the wisdom of MLK. The power of taking the high road. To being a better person than your adversary.
Christian Cooper is a better person than me, and that's a more powerful message to white people like me.
