Here is an oldie but goody by that great Cathedral guide Gagdad Bob.
"...But who controls the present also controls what is defined as "normal." Therefore, since leftists have taken over most of our institutions in the last 30-40 years -- the media, academia, the courts, the educational establishment, Hollywood, etc. -- they have been engaged in the unyielding project of redefining normalcy -- of defining deviancy downward -- so that the abnormal appears normal and the normal abnormal.

It begins with their radical cynicism, which throws out all intrinsic hierarchies and standards as arbitrary and subjective, supposedly motivated simply by the desire to dominate, control, and oppress. Therefore, to believe things as banal as "terrorists are evil," or "children need a mother and father," or "marriage consists of a man and a woman" is to expose oneself to the ridicule of people who do not know what normal is -- nor do they want to know. .."
