You just repeated what I said, except you misunderstood it and said things that are false like:

I guess the difference is that the US has started killing white protestors now?

That's not new at all.

From the mid-1870s onward, violence rose as insurgent paramilitary groups in the Deep South worked to suppress Black voting and turn Republicans out of office. In Louisiana, the Carolinas, and Florida especially, the Democratic Party relied on paramilitary "White Line" groups, such as the White Camelia, White League and Red Shirts to terrorize, intimidate and assassinate African-American and white Republicans in an organized drive to regain power.

But the most important part of the lesson, is what happens when people put their personal safety over societies well-being:

In Yazoo County, Mississippi, for instance, with an African-American population of 12,000, only seven votes were cast for Republicans in 1874. In 1875, Democrats swept into power in the Mississippi state legislature.[46]

They used violence against anyone who didn't agree with them, so people who didn't agree with them stopped voting.

And the racists still have the political power in the South.
