Strumia clearly did mislead CERN and the workshop organizers, pretty clearly gave a presentation to troll the workshop, and clearly launched an attack on another scientist (present at the workshop) during his presentation.
Is your argument that someone should have been able to give a contrarian presentation about gender disparities in physics at this workshop? I agree with you. But that's not what Strumia did. He tried to pwn the libs, and ended up depantsing himself.
His dismissal is not an objective nature of the inherent 'offensiveness' of the presentation.
This was not something that came from within, this was forced from the outside namely the media, in this case, BBC which made it politically problematic for CERN.
If a woman or man had launched an attack on the problems of being a woman in a male-dominated field nothing would have happened, in fact, he or she would have been applauded for speaking truth to power and celebrated for their courage they certainly wouldn't have ended up being called sexist or wouldn't have their ties cut.
You might as well chose to read him in the same manner, he certainly did think of himself as someone who spoke truth to power.
And it certainly wasn't something that was a bigger problem than someone could say. "What an idiot" and then move on.
But no, this had to be a question of sexism even though he was talking about discrimination against men.
This has James Damore deja vu all over it.
The code of Conduct hail mary is an excuse which is why their apology is not an argument it highlights the very problem.
There doesn't seem to be any evidence of that. How do you imagine the BBC found out about it?
