What do a lot of people care about that you don't understand (see details)?

Wow, that wording is confusing. What I mean is this:

Is there anything that you see a lot of people caring really passionately about and you just don’t get why? Do people talk about this topic a lot and it has you wanting to scream, “Who cares?! It doesn’t even matter!”

And I don’t mean that you feel strongly about an opposing viewpoint. You may not understand why some people think abortion is okay when it so obviously is not (ahem, sarcasm), but that’s not what this question is about. If you don’t give a hoot about abortion either way and don’t get why people care, that would fit nicely here.

Of course, we all know that everyone feels strongly about different things and they have a right to feel that way, but this is just for fun, so let it out!

Inspired by this question.
