Nope. I don't consider PyCon a "professional conference." Programming is not accountancy, or medicine. "Professional" is a word that people use to lull people into circumspect behavior leaving their basic humanity aside. Sometimes there is a good reason for it but often there isn't. In any case it's not a way of being at ease.

When I am with my close friends at a conference we speak however we like. It isn't church and it shouldn't be. But I'm sure now that I'll never go to PyCon. It's drowning in the crazy.

My sense is that this is largely generational and geographic. There's a strain of political correctness in the California area that is rampant among people in their 20s. I don't see it elsewhere in the US although I have seen it in Canada. PyCon is definitely a California conference.

I'm sure the educational system has something to do with it. It's a trend that rode the general trend in education in the 90s toward making people believe that feeling good was more important than anything and that their sensitivities were positive demands on other people's behavior. That's subsided since then in elementary education so I think this drama may be a blip.
