The left and Democrats are always playing the race card. They want to divide people up into voting blocks. Identity politics. You're perpetuating it with that attitude. All lives matter. All Americans matter. We shouldn't play favorites with anyone. That's how we got into this mess in the first place.
White lives have mattered since the first European set foot in this hemisphere. Black lives, not. They didn't matter at all for 250 years except to the extent they were property with monetary value. And then for another 100 years they didn't matter in much of the country. Black people could be lynched, whipped, burned, shot, raped, and tortured with impunity by the whites. So the slogan Black Lives Matter really means "Black Lives Matter Too" and the people who go around shouting White/All Lives Matter are being disingenuous or just plain stupid.
As for playing favorites, I agree we shouldn't. This country has favored white people, men in particular, since day one and is still doing so. So let's stop.
And the race card? Please. That has been played by the white supremacists for ages. Remember the Willie Horton ads in the 1988 presidential campaign? Dog whistle politics in pure form. How about the "southern strategy" where the GOP used dog whistles and code words such as "states rights" to communicate to white people, particularly in the south, the GOP's willingness to oppose civil rights laws.
And identity politics? That has been Trump's calling card since day 1. The identity is, of course, aggrieved white people who fear that their dominance will end.
