Tolerance is a social contract not a right. If you are tolerant, you earn tolerance for yourself. If you are intolerant, you don’t deserve tolerance yourself. It’s really not that complicated imo. I don’t feel the need to be tolerant of racist, bigoted people.

Ah interesting one of those cases where this could be one of a few languages. I was reading it as JS.

Yea uh is this actually equivalent? In all of those other cases you’re checking if a is null and in the last case my understanding is it is checking to see if a is falsely. In the case that a is 0, or undefined, or an empty array or any other kind of non null falsey value, then the behavior would be different.
