Would it ever be possible to not see certain people's posts on your threads?

Sort of like a block function, but not from answering at all, but just so that you wouldn’t have to see them.

For example, there is this one person on this site who seems to be completely ignorant of affirmative action, even when given extensive resources. Every time I ask a question that has to do with race, politics, or government, the person seems to start picking little fights with me. I can ignore it, yes, but that doesn’t always work.

I don’t know, maybe it would help me in my patience, but there’s only so much that I can do before I tear my hair out.
