It is true that all Muslims are not terrorists in 2010, but all terrorists ARE Muslims. The only reality that is possible is to not allow Muslims to fly. It is now up to Muslims to prove beyond a reasonable doubt that they should be allowed to board planes with other human beings.
It is not the responsibility of the rest of humanity to prove a negative, which is that this particular Muslims bears us no harm. One of the central problem of civilization in the 21st Century is that Muslims and Islam generally has refused on all levels to take responsibility for their actions. And, unlike Christian and Jewish believers they are not held to any level of responsibility by others.
It should now be very clear that one cannot ever stop the means of carrying out terrorist attacks, they can only be stopped by going to the source. By profiling the ones who are willing to commit terrorism to go to a better place. Profiling always works.
Political correctness (PC), especially in the United States, has harmed, and continues to harm, our national security. There is no question about that. Look at Ft. Hood and the flight in Detroit. There is only one solution: go to the source. This has been the ONLY way to stop terrorism. Otherwise expect that Americans and many Westerners will die in the future for the sake, and solely for the sake, of PC
