It is the ultimate in control to prohibit words from public use, with public punishments from demands of apologies to name calling to seeking to remove people from their jobs.

I have posted on the power of political correctness that is going on in England. Many young girls were exploited and raped by Pakistani men who had them in prostitution rings. This went on for twenty years and though it was reported to child services and the police nothing was done about it because everyone was scared of being called Islamophobic. Political correctness is extremely dangerous, it is the modern day equivalent of the Salem With Trials.
