I typically don't concern myself with what makes other people's neurons fire in unique ways. The only exception is if/when the person is a part of my life and we're being intimate. If they want to share their "unique buttons" because they hope that I am willing/able to press those buttons for them? Then I am more than happy to listen, to talk, to ask questions and to learn about what special triggers they have inside their skull. No judgement, no squicking, no hate. Let's talk and see what the other thinks. Similarly, the strange quirks inside of my head? They are mine and unless I want to share them with someone else, they are staying inside of my head where they affect no one, harm no one, and impact no one. So, since I live in a "glass house", I am not inclined to throw stones and label someone else's interests/fascinations as either "worst" or "dumb" or any other such adjective.
