<Snipped quote by mdk>

Sure, except me choosing not to spend time with someone, or to pursue a personal connection with someone, is hardly a systemic system of oppression. I certainly have plenty of friends and acquaintances with whom I don't see exactly eye to eye. It is certainly possible to agree to disagree, but there are position which I would consider not just wrong but immoral. Racism springs to mind as do things like sexism and homophobia. If someone expresses such an opinion, it doesn't seem like tolerating that person in my life is morally acceptable or at least not morally consistent. [/quote]

Certainly there are positions bad enough that cutting ties is justified. We could think of those on a case-by-case basis. Using those extremes to justify things like "Well, you voted for Trump though, I'm unfriending you" is where it becomes childish. There's a lot of childish people in today's America, largely because schools (especially universities) have been growing into liberal echo chambers for generations, and we're not teaching our children how to handle other POVs (case in point, that woman who stabbed a police horse in the neck with a bladed flagpole because people nearby were supporting the president).
