The power of an argument is plainly not "force" in its own right. Nit picking a figure of speech like "forced to confront" is not a persuasive point.

> That you/they take it as a moral right to force people to do anything, even to consider some point, demonstrates the very moral corruptness that people hate about vegans.

I think in no other context on Hacker News, which is a hive of far-reaching intellectual curiosity, would it be taken as a negative to claim that confronting someone with a possibly uncomfortable point would be taken as moral corruption.

(Note that 'forcing' here is not in the sense of, say, using physical force to compel someone; it is just in the sense of presenting information, so that people's only possible responses are to consider that information or somehow to ignore or discount it without acknowledging it.)
