Rational people is a very vague word; in particular, I assume most people consider themselves rational, but not necessarily others. Personally, I consider people who were protesting Brendan Eich's position as CEO of Mozilla based on some past, popular (i.e. consistent with majority opinion) non-violent non-crime, but are not protesting Condoleza Rice's position on Dropbox's board or Israel's attacks on Gaza, to be highly irrational. But there seems to be a lot of them (especially in the media), and they have proven to have huge destructive power, so it makes sense to hide stuff from them.
