I have a side of the family that still supports Trump. That same side of the family has interracial marriages and there are black babies that are very loved upon (and no, it wasn't some scandalous thing, the relationship and the marriage was uncontroversial).
Clearly, those members of my family are not voting for Trump because they're racist and afraid of skin colors.
They're (in my understanding) voting for Trump because the older members when they were younger had more economic opportunities and felt more attached to their community and their faith. I don't agree with them on priorities, but it's not racism, it's in more ways a sort of nostalgia for a time period when life didn't involve so many complex and nuanced topics.
I know you mean well, but it's fine to discuss your family at a level you feel comfortable. Your family is part of your experience in the world and that is fundamentally a part of your political perspective.
It's not my problem that some people on the Internet want to insist they're the expert on everything, even people, people they've never met.
When it comes to people, we should all try and keep an open mind about what perspectives might exist. These narratives that people are so divided, that Republicans are racist, greedy, and narcissistic, and that Democrats are handout seeking, weak, and naive ... they need to be challenged (and first hand testimony is important but often seriously lacking).
If we're just going to deny another person's experiences are real anytime they don't align with our world view ... what's the point of even being on a forum?
