>If somebody finds any of the below to be objectionable and refuses to abide by it, I would not be comfortable attending a conference with that person or being forced to interact them for e.g. code review purposes.
Not me. I would perfectly comfortable interacting with such a person, because I'm a mature, professional adult who is not a fragile child that needs to be treated like a kindergartner. I will go out of my to not work with the adult babies who think the world should revolve around them, and have to politicize every aspect of life.

IOW, say something we don't like, and you're gone.
