You will hear people say the C-word. Except, it's a regional language: in British English, c - t has much less of an inflammatory sense than it does in North American English. You can hear someone on British TV called "a c - ting monkey" or a man being called a c - t. The particular fascination of profanity is how culturally specific it is and how it evolves.

I certainly self-police my language depending on who I'm talking to. I try to be very careful about using filler words, about not drawling certain vowels, even when I can't say "drawl" without drawling. That's kind of sad, because self-policing inhibits communication. You're more focused on the words coming out of your mouth or that should not be coming out of your mouth than making a connection with the person you're speaking to.

I think when dictionaries define words, there's a sort of hair-splitting that to most people doesn't make any sense, which is we're not describing what a thing is.

With "marriage," the word gets applied to same-sex marriages by proponents and opponents alike. That means the word itself is changing, and we reflect this change. But because of the idea that the dictionary is the objective voice of authority over culture and knowledge, it reads like approval. It's not a helpful way of looking at lexicography.

The history of English is full of that, lots of things done with good intentions that 200 years down the road have resulted in a giant mess, where someone's pet peeves - like John Dryden and his hatred of terminal prepositions - could become real standards.

Words have always been political, and that means that, in many people's minds, dictionaries are political. Because that's what dictionaries do: they do words.

A lot of people thought oh, we caught the dictionary in racism, or all it takes is a whole bunch of people saying that a word is bad for the dictionary to change it. That's not the case. For nude, things that are called nude color, that color palate has broadened very recently, in the last maybe seven to 10 years, and now covers all skin tones.
