Question:

What is the Philosophy behind Political Correctness?

What is the Philosophy behind political correctness? Is it trying to please everyone? If so what about the phrase "Try to please everyone and you will please no one."

If it is about that then it has already failed due to the fact that I personally, and I am not the only one, find it offensive.

So what is the Philosophy behind PC, and is it doing it's job?

Serious ansers only.

Thanks.

Best Answer - Chosen by Asker: The basic philosophy behind political correctness is socio-economic justice and progress for all....pursuit of collective wellbeing that is just and fair towards everyone..... meaning equitable share in progress rather than equal share.

This philosophy is being blatantly overlooked and flouted due to pursuit of power having become the sole objective. In democracies, therefore, it has become a game of looking after the partisan interests of major groups at the cost of the interests of the minor groups, because power is vested in numbers. In other set-ups, it could take the form of alliance with power wielding groups such as the military establishment or the elite class or religious leadership or even a powerful neighboring country. Political correctness does not seem to exist anywhere, barring a few idealistic leaders struggling to make their voice heard and heeded to. Politics having become a power game, has thus also turned into a playground for corruption and cunningness.
