When you believe it's reasonable to have a discussion on whether your children can be friends with people from a different racial group, and then you find a way to tie this into Trump and his supporters being "racist"
To answer your question, yes. Your children can be friends with white people because white people aren't a collective that likes to consciously or unconsciously oppress minorities at every turn they get in order to "maintain their hold on society." Also, stop blaming Trump and his supporters for every single damn problem; you are giving the man too much credit.

My best friend from elementary school was black, we didn't think it was strange at the time. Raise your kids with the idea that you should judge people based on the quality of their character, not their skin color. That's how you end racism
