Some things aren't worth weighing in on.

For example, you go to work and some of your more braindead colleagues are earnestly insisting that keeping a list of amusing customer names is the first step on the road to genocide.

Do you: (a) get involved in this nonsense, knowing from past experience how furious they'll get if you disagree, or (b) ignore this stupidity and get on with your job?

Personally, I'd pick the latter.
