I personally find it very annoying when people hate on a moral standpoint not because of its values, its beliefs, or anything like that, but because a few people with said standpoint were being somewhat rude about it.
For example, I've seen a lot of people say they're anti radnormal or radnormals are in their dni list, but they uphold the same values and beliefs radnormals do. It's just because they see a few people harassing others who just so happen to consider themselves as radnormal and therefore literally everyone with that standpoint is immediately assumed by them to be an asshole.
I would argue against harassment right now, but that would go off topic, so I'll simply state the obvious fact that, yes, all harassment is bad and you are an asshole for harassing people and making a group of people who only have a moral standpoint in common with you look bad. But it's also insane to judge a viewpoint itself based on those who have said viewpoint and disregard what is stated to be what it stands for. Not only that, but if people in a particular group you hate only rarely exhibit habits you hate them for, then you should really stop hating them on principle as you've no reason to. It is, after all, a very small portion you are criticizing and one likely hated amongst others with beliefs similar to theirs in areas other than harassment.
