The purpose of civility
is to make people comfortable
and at ease
. Part of civility is to not refer to people by names they (and, lets face it, you too!) find offensive. It has nothing to do with your political agenda
, it is downright civilized behaviour
. Any discourse, personal or public, that uses slander or offensive, diminutive and contemptuous phrases intentionally
is inciteful and non-democratic. One of the basic principles of democracy as I see it, is the ability to respect even your opponents.
Political Correctness is a way to avoid showing such disrespect even to your adversary.
