Most of the time when people say they have an unpopular opinion, it turns out it’s actually pretty popular.
Do you have some that’s really unpopular and most likely will get you downvoted?
Their argument has a lot to do with people not establishing context upfront unlike your example with “someone called”. I can’t count the number of times I’ve had a conversation with someone talking about a non-binary person, only to realize five minutes in they weren’t talking about a group of people. It’s super jarring when it happens.
