The fact you keep saying this makes you look so short sighted and thick it's unbelievable.
You're obviously an intelligent guy but you can't appear to grasp the actual point here. The fact you say anyone disagreeing with you is offended just paints you out as being short sighted and narrow minded. You haven't managed to give one reasonable argument about why banning the word is bad other than people shouldn't be offended.
I honestly had the exact same opinion as you, but reading a lot around the subject made me appreciate that maybe I just didn't understand how it feels for people who are the ones affected.
Sometimes there is nothing wrong with holding your hands up and saying "I don't understand this and if it makes people's lives better while not making anyone else's life worse why not try and understand it"
