LeninGrad, I know that this was a conference with attendees of all genders, races and religio-political persuasions. And I absolutely agree that the presentation was offensive, unnecessary and bang out of order.
The only equality and respect policy that should have had an influence on this particular instance is that of the organiser. He's already put his hands up to admit that he badly blew it.

As for the underlying principle... Nope, sorry, I'll not condone anything that smacks of the thought-police. I don't particularly care what people think on the inside; it's what they do on the outside that matters.
People have an automatic, in-built tendency to pre-judge situations and other people. That could be a man regarding a woman as a sex-object or a woman thinking a father will never be as good a parent as a mother. It's part of how our brains are wired - you get a fast, emotional response.
The crucial thing, and the thing that separates humans from animals, is that we can then use our intellect to overcome those knee-jerk reactions by mentally putting the situation in a wider context and with a more dispassionate view (or not, as in the case of Daily Mail readers ). It's by balancing the emotional with the moral that we can choose to do the Right Thing.
Feelings are complex bio-chemicals sloshing around our synapses in reaction to a given stimulus. They are what they are. It's actions that show the worth of a person.
