We could further ask, do we want to be smarter and more productive? I always keep thinking about another research I've read about ([0] seems to be an article about it that I found just now, but I haven't searched hard for any rebuttals) that diverse communities experience less trust and less civic engagement. Basically, it makes sense that similar people want to stick together, and personally I see no reason why we shouldn't let them! (Conversely, those that prefer to live in diverse communities should also get the choice.) Another example is, plenty of Brexit voters knew that Brexit would be bad for economy, but supported it nevertheless because they expected other benefits to outweigh it, so I don't think arguments concerning the economy should overrule all other considerations. Btw, I disagree about free speech - it seems to be pretty dangerous (career-wise, if not life-wise) these days to offend people (see Tim Hunt, Donglegate, Justine Sacco). I guess my broader point was embedded in my original post - these questions have multiple answers, but not necessarily the right answer. People have different opinions and priorities, and they're not necessarily better or worse, just different. I think we should respect that and accommodate this kind of diversity ("opinion diversity") into our society, not try to exterminate it by shaming those that disagree with us and trying to change their minds. This is a great article that describes such a world: [1].
