There's probably a reason they have to tout that, right. I think one of the most reliable lines I've encountered like that is "I don't like drama". People who say that tend to always be involved in drama, which is why they have to verbalise that they don't like it in the first place. I also do not like drama, but I don't verbalise this, but rather I just avoid it.

If you have to say "dont be a jerk", rather than just do it, what does that really say?
