Buddhism and political correctness

I stumbled upon a question about the danger in lying and Andrei's answer caught my attention. He claims that '...key qualities of good character are: Honesty, Integrity, Responsibility'. Then it made me wonder - is being politically correct an obstacle on the way to enlightenment? By the term political correctness I understand 'enforced language, ideas, or policies that address **perceived** discrimination against political, social or economical groups ("protected classes")'. >It seems that: > >Lots of public figures no longer say what they really think but they mince their words so as not to offend any of the groups. > >Media doesn't report certain facts/events/results of studies in fear of offending groups which won't feel comfortable with certain facts/events/results. > >Most of the time it is not based on honesty. > >Clearly this leads to violated integrity. > >In everyday life we also seem to be forced into political correctness. > >Challenging someone's views can be **perceived** as an attack and more and more jokes are **perceived** as offending (although it used to be a great virtue to be able to laugh at oneself). I would be mostly interested in what *contemporary Buddhist teachers and masters* think about this topic. Please refrain from sharing personal opinion if it's not based on specific teachings. I am looking for advice from Buddhist masters and texts mostly.
