It’s ok. You can’t talk sense to white leftists either.
I think you might get farther talking sense to black people than to white leftists. It is so pathetic to see a white person arguing for the “BLACK LIVES MATTER” bunch and apparently ashamed of being white. We have one in the family who claimed that Barack Obama was cutting spending to the point that BOTH the annual deficit and the national debt were falling. This was just after the 2012 election. I didn’t waste my breath trying to convince this middle aged math whiz (he actually is one) that it was impossible for both to be dropping at the same time. If there is a shrinking annual deficit there is still a deficit so the national debt has to be rising. If the national debt is shrinking there cannot be an annual deficit, there has to be an annual surplus to shrink the debt.
