Are Liberals selling out the Western world to those who hate our way of life?

In recent times, people like Geert Wilders, Pam Geller, Rob Spencer, Allan West, Wafa Sultan and others have had, and still have critical views of Islam. Every time they address problems that radical Islam or Islam itself, they get called racists, xenophobes and islamophobes by Liberals and some Muslims. Why do Liberals act like the right is their enemy? Why are Liberals busy being politically correct, rather than calling things by their names? Do Liberals want the West to disappear? I don't understand Liberals at all. The media, churches, trade unions, libraries are treating those who are exercising their right to free speech, by addressing problems that the West is facing as racists, far right etc. What's going on?
