What seemingly random thing do you vehemently hate?
Hate is a strong word, with or without vehemency.
There are things I despise (most media, social or traditional, being an example of), there are things I don't like (bananas), stuff and behaviours I disagree with (certainties and personal opinions used as indisputable truth, violence), and then there are people I dislike, some deeply (like... nope, I won't name anyone) but I'd rather not hate. Not anymore, like I may have hated when I was younger.
Hate helps no one solve any issue, helps no one in becoming a better person. It certainly does not help me, quite the opposite.
