I'd say I care about two things in this case:

a) to understand why people are so worked up about this man and his antics. I think it is very interesting because it can also reveal something about myself.

b) interesting, novel conversation that broadens understanding

I don't care about the man or his antics or predictable conversations that are boring.

But I think you've hit on something true: I should just move on and let people churn on this stuff and don't get entangled myself. Thanks for pointing it out.
