Why this bothers me so much:

I read something really good once about how you cannot always be both fair and polite. Sometimes, to be fair/just, you have to be impolite.

I really hate it when people are polite and use nice-sounding phrases for ugly things, jettisoning justice to achieve it.

Sometimes, you can be polite at the expense of being accurate. (I was explaining this to my five year old son, in smaller words, as he was pointing out to me that a nearby woman was fat.) I’m against being polite at the expense of being fair.
