I don’t think this is an unpopular opinion. I make my bed as my bedroom can be seen from the living room; sometimes I leave the door open. Otherwise I don’t care.
Unsure about the bacterial concerns you have tho. Feels like a non-issue as long as your sheets are changed frequently.
I think some people make their beds as to them the room looks untidy if they don’t, its just preference. But it is definitely a boomer generation thing, my parents were the same.
Ah, so attacking someone and making a scene is going to fix this how…?
