What's interesting is if you look at something like corporal pinishment applied to children.
It's still legal in many countries and many states of the US for someone to physically assault your child and as a parent you have no recourse. Not only is it legal, it's practiced regularly - especially in the more religious states of the US.
That seems a far more clearcut violation of a basic right and the description of what is deemed to contravene it than someone simply refusing to talk to someone else or invite them to a family event. i.e. it's an actual act, rather than the absense of an act.
And yet it's not against the law and happens hundreds of thousands of times a year and with a disproportionate number of the either disabled or an ethnic minority.
Are we really to believe that the world is going to be bothered about a minority of people suffering some emotional harm in comparison?
