Yes, this would be an excellent feature. Only problem is people exploiting it to hide or ridicule legitimate responses they don’t agree with. But that’s a problem for later. With the cussing userbase and growth rate this feature works be great for quite a while.
I wouldn’t necessarily say ‘stupid’. But lacking in sufficient empathy? Fearful of different people (to the point of being irrationally hostile to them)? Feel entitled? Are smug and sanctimonious about their beliefs? Get to caught up on what other people do with their lives and want you control them?..
Then yes. Definitely.
