Who’s being unkind...subjectively calling out a group of people (I.e. an entire state) for being worse at something (unless “dippy” is a compliment in CA) is not kind. It’s annoying because is just false.
You’re open to your opinion but if you share it others are not always going to pat you on your back for it and they may just do the opposite.
Pretty simple, if it isn’t nice keep it to yourself
