I think you get most of it, I was trying to convey that if you say something to colleagues at the workplace that is too disrespectful, sexually suggestive, vulgar or sexist to mention in front of either of your parents, it's a good common sense "warning flag" that it's probably not safe for work. I struggle with this myself, having a dark sense of humor. I hate seeing the perfect set up for a raunchy/sick punchline going to waste, but I'd also like to keep my job :)

Politics is a bit of a gray area. It's very easy to make people uncomfortable without realizing it, it's just a shitstorm waiting to happen. I try to avoid it unless I'm speaking in private with a colleague who I know extremely well.
