Where I live conferences are considered a workplace so our strict equal opportunity and sex discrimination acts apply. Under these acts, crude conversation and jokes are considered to contribute to a hostile working environment. In the event the someone (male or female) is offended, intimidated, or humiliated they are at liberty to file a sexual harassment claim. The intent of the harasser is irrelevant. It can be a single incident or repeated behaviour and the victim is not required confront their harasser. The parties need not even be employed by the same entity.

Of course these very same laws require that the claim is filed confidentially, and the kind of public shaming we've seen here is itself considered harassment.

If PyCon had been held here the only party with their noses clean would the conference organisers.
