I have occasionally used rude words on this blog. So do my commentors sometime.
I do not intend to interfere with that.
I never use the NewSpeak about race, etc. unless I am quoting or being ironic. As I have said, part of the great power of PC is the imprisonment of thought by the policing of speech. Breaking those rules as often as possible is necessary for actually thinking and seeing reality.
Be it polite or not, that matters not to ExC.
