It’s no secret that humanity, as a whole, is becoming a lot more sensitive. Everything that is intended for public consumption has to be heavily screened for political correctness – set one foot wrong, make one ambiguous statement and some affronted group of individuals is going to take offense.
This isn’t exactly new – it’s human nature to look for the negative; people like to have something to protest. The difference today is that society is accepting these complaints; we nurture them and lift them up and make them rational – they’re not.
