As a non-technical person, someone on Reddit once explained in a way that makes sense to me as an analogy. Say you are on vacation for a week. Over the course of the week you get pretty good at going from point A to point B, and can even take small side trips along the way. But one day you get a little turned around, and you find you can’t get back to where you need to go. But if someone could pick you up and return you to your starting point, you could do just fine going about your business.

I don’t understand why, when people talk about what a dirtbag Trump is, so many people respond with, “Yeah, but person X is also a dirtbag.” Like yeah, so? That’s beside the point of this conversation. That person is also a dirtbag. Why don’t you start a thread to talk about that?

In my line of work, the “Bible” is the Chicago Manual of Style. It is the deciding factor of what is “right” in editing.
