Thank goodness they aren't. Unfortunately, the bigoted ones seem to be the loudest and most repetitious, even in my own family, if you consider West Virginia (KKK Grandfather) and Kentucky (related by marriage)
I barely speak to a brother because he has never lost the bigot mindset, although he doesn't use the N word around me when he refers to my grandson's. But that took a short flight across the kitchen for him to understand that. My hand never even hurt afterwards.
As for missing the point, you confused the issue by bringing in a second group of extremists, starting the meme off with a series of attacks that focuses on incidents that you are using to justify a white supremest mass shooting.
This is one where you needed to state your case first, then use the other incidents to back up the statement.
But it'll be difficult if the mass shooter is from South of the Mason-Dixon line.
