I forget who I was snarking about at the time. Probably the interests of one of my siblings.
She (gently) reminded me of how people sneered at me for being interested in SciFi and history etc. Asked how that made me feel, and if I'd want others to feel the same. Smart woman.
Her point was you don't have to like a thing, but should always try to learn a bit and see WHY others do. Because people being interested in things is always fun.
