Political correctness will cease to exist in America only after some form of mass destruction or death. Here is a scenario - what if China rattles their war sword and surprises our 7th fleet by detroying all or nearly all of the ships in a major carriar battle group. We have over ten thousand dead, ships sunk and destroyed, billions of dollars lost. And then it is found out that during the Clinton years, information was given to the Chinese that enabled them to do this. People knew about but were told to be quiet because we did not want to offend any Chinese. What would the American public do?
Another case - PC is enforced to such a degree that we not only do not profile but judges are forced to turn loose the people the DOJ have. Then a dozen or so of these people that were in custody take out - let's say - five nuke power plants. Tens of thousands of people are dead or injured, millions of dollars of property is rendered useless, power is out for major parts of the country. The rest of America finds out that because people were afraid of offending Arab-Americans, we either let terrorists roam or let them go free to cause death and destruction. What would the American public do? Would PC be thrown out the window?
You paint a damn scary scenario, unfortunately, it could very well happen. We know that Clinton facilitated the transfer to China of our nuclear launching capabilities...that in and by itself, is scary indeed !!
