Surely, every adult person knows the difference between acceptable and inappropriate behaviour? If not, they must be socially dysfunctional, abusing their power, and/or just plain dirty old men (or women).
These allegations seem to go back quite a few years, and why didn't these women just slap him, knee him somewhere painful, tell him to F*** Off or just shout out "Oi - get your hands off??!"
If true, the fact that he wasn't taken to task before speaks volumes. Maybe in political realms women, unfortunately, are seen as 'fair game' in such a male-driven area. Also, someone had to sign 'gagging order' - always a red flag.
