Sorry, EV - don't agree.
There is a difference between 'banter' and ribald comment and what actually happens on the occasion.
There is of course all sorts of innuendo but the overriding situation of an 'at home' is the entertainment of ones' guests and ensuring that everybody enjoys themselves. There will, sometimes, be a bit of showing off but I have never been to a social event of this sort where there has been any delberate lack of civility towards the guests.
As to 'ogling' the opposite sex, there is a world of difference between finding a member of the opposite sex attractive/personable and stepping over the line. The phrase; 'you can window shop but not buy' probably sums it up.
As for your complaint that MM left his wife at home with sick child whilst he went 'on the pull', is unworthy of you and you should retract.
Old Duffer - in pompous mode again.
