Liberals are taught the dogma that "everything is relative" and there are no absolutes. No absolute laws that can't be bent or broken. No moral principles that are firm and unyielding. They are taught through their sociology and anthropology and psychology 101 classes, and comparative religion classes, and intro to this and that, to take other cultures' perspectives on things and don't judge the behavior or culture or values by your own values. In fact this style of education breaks down the concept that an individual can even HAVE personal values. There are no ethics, just situational ethics, do whatever works.
Freemasonry "Do what you will" will be the whole of the law. Same principle.
No definite right and wrong, to each his own, change your mind whenever it's convenient.
This kind of liberal education has been going on in colleges and universities since at least the 1970s and I presume much earlier.
