Objectivity and moderation, sadly, seem to be considered negatives at this time -- at least by those who are controlling the conversation with their volume and anger. Civility essentially equates to capitulation.A form of 'civility' is inherent in proper use of language. For precision and clarity, one needs to speak with some objectivity. That necessitates the avoidance of immediately inflammatory and pejorative expressions. Morality and ethics are almost apart, another subject. They will affect the use of language, but not necessarily effect it.
And even more problematic is the fact that many on the ends consider themselves perfectly objective. Their perceptions are distorted by their ideology, but of course they don't see that.
