Well I'm glad something useful came of my ranting. First time for everything :D
Personally I agree with Morgan Freeman on this issue:
I think culture helps to divide us too. Although without either I think humans would still try to find things that make "us" better than "them." Because "they" are less intelligent, too old/young, disabled, worship the wrong deity(ies), like the wrong sports team/event, listen to the wrong music, eat pizza with the wrong toppings, voted for the wrong political candidate(s)/cause(s), have too much/not enough money, et cetera, et cetera, et cetera.
But the race issue, pretty much why I hate Trump. Now that he's in charge, even if he's not overtly racist it seems like all the racists think they have some type of validation. The amount of racial, antisemitic, and homophobic attacks have gone way up. I'm hoping we survive until 2020 when we can finally vote him out and start healing.
