I'm not trying justify his use "gay", "sh*t", or retarded. I should have made that more clear. He posted what he did and consequences happened. What I mean by nuanced conversation is two people could be chatting about something they find entertaining, using tone or words that others might find offensive. Jokes are a prime example, where I know plenty of people who like Dave Chapelle's stuff, but I know there are those that are offended by it. I've seen Twitter posts in the past where that pretty much happened.
