That’s a great way to pose the question as it has happened in different ways over the course of American history. Whites who proclaimed themselves as abolitionists in the 1830s to 1860 were targeted by whites, not in the South, but the Midwest and North even. Many were lynched. The reason they were more heavily “hated” when they came out then black Americans was in their ability to take their grievance against white supremacy to end slavery to the heights of political power that blacks didn’t have access to. It’s easy to hide when white and anti-slavery but once you show your face, you got targeted. I was reading about a couple “terror incidents” when abolitionists tried to speak and blocked from doing so on Staten Island and other places. Of course white civil rights workers were shot and killed in in the 1960s.
