To be honest, I don't think you should revise your writing based on what just one random LWer (me) thinks. I just wanted to share the discovery I made about canceling upvotes, which was new and unintuitive to me. If I had read your last paragraphs before upvoting, I would have just refrained from voting in either direction and I would not have written any critical comment.

If you really want to know, though, the part that bugged me most was the paragraph immediately after the quote. ("Social justice in action…") It is snarky; maybe not towards Nancy as such, but certainly against the general opposed political position. I think the "no mindkilling" general code should preclude using snark in a political discussion, since its purpose, roughly, is to lower the status of the opposed viewpoint without adding substance (relative to a non-snarky rewrite).

But as I said, I doubt you should care too much about this opinion and rewrite your post.
