"kneel to make sure everyone knows the sun will rise tomorrow."

In other words, kneel to state the obvious, ComCon?
In that respect your analogy is more apt than I think you intended.

It's obvious for multiple reasons that blacks are often treated poorly by whites: it's as predictable as is the likelihood of tomorrow's sunrise.
That ongoing predictability is precisely why BLM and some NFL players are protesting.

I remember very clearly the emotions that swirled around the civil rights activities during the 1960s. Whites felt very threatened by all those negroes (and courageous white supporters) marching in the streets for things like integrated lunch counters, integrated schools & universities, registering to vote, etc.

During Little Rock, Governor Faubus said something like, "In Heaven's name, what is happening to America?"
Sixty years later, we have exactly the same feeling.

The negroes were right then.
The African-Americans are right now: things are still a long way from fair.
