Thing is with Facebook people post stuff like that ignorant of whether it offends or could be potentially sensitive because they find it funny and then legitimise trivialising it by saying they are doing their part to humiliate. It's crap. You'll get the free speech nonsense too which from a rights and debate perspective is something I agree with but there's a difference between that and blanket posting stuff because you can. Too much is played upon by people on Facebook citing freedom of expression. Have done empathy and common sense ffs.
