I fundamentally disagree with the whole "am offended by your use of language, you are the one in error" approach to solving any problem. You never had the right not to be offended.
I suffer from Tourette's, meaning that during high stress situation for me such as a conference I am certain to utter words that are 100% sure to offend someone. The thought that this now is likely to have severe adverse effects on my conference experience such as being thrown out and being publicly shamed for it (like people have done with Mark despite the point of his talk and the use of the imagery/words clearly was not to cause offence). And I don't even have to worry about longterm effects on my job situation, whereas I imagine other people do, and don't tell me there won't be any, accused, mistakenly or not.
I will never attend any conference which upholds any such anti-harassment policy, it is simply not conducive to having an enjoyable time and it is likely to end with undeserved pubic humiliation on my part.
To see this in any way declared a victory is painful, everyone was a loser coming out of this, especially Mark.
