This is proof the Left won the war, or believes it has, and are now trying to consolidate power. In the old days they would tolerate, even promote, some humor (like George Carlin) that was actually funny as long as it did not go after them. But now there is no humor at all; watch The Daily Show and see if you get so much as a wry chuckle. You won't.
That's because they can't allow people to laugh much lest they start laughing at THEM.
It is also a psychological tool to break down the resistance of the individual to their programs. Humor was God's great gift to Mankind to deal with tragedy and loss and suffering. Get rid of that and you "rub raw the wounds of discontent" as Alinsky also advocated. An angry populace is a divided populace and one willing to accept a radical solution.
So humor has to go. And the Left is doing their level best to stamp it out.
The best way to fight the Left is to turn this tool against them - laugh at them. Do it often, do it publicly, do it loudly. Don't let the bounds of socials convention act to restrain you in this because such bounds are being used as a weapon by the Left to disarm us. They have pushed the Overton Window far to the Left and we need to start pushing it back to the Right and the only way we will do that in our culture is to make people laugh. And let's face it; they are ridiculously funny!
There are a lot of Christian Conservatives who won't do this on the theory that it is unchristian but remember we are not laughing at people necessarily but at hypocritical and ridiculous IDEAS and those who engage in the Kabuki theater to promote them. A bearded ma who insists on going out in public in a little girl's nightgown has to be laughed at - there is no better response, and indeed he wore the thing with the intent of shocking and attracting this very sort of attention.
The Soviets did this all the time, putting forth some ridiculous proposition and daring people to deny it. It was a pure power play; everyone would be too scared to say anything, thus reinforcing the lesson that the Party had the power, and in fact most would go along with the insanity, which made them party to the lie and thus helped wed them to the notion that reality is fungible and can be changed by the command of the Party. It was how they could tell their sleeper agents that America was dirt poor and oppressed and these agents could come here and live in what to the average Soviet citizen was fabulous luxury and still believe it. It's a brainwashing technique. Oh, and it WORKS! The Soviets actually used Three Stooges shorts and claimed Moe was an example of how a capitalist boss treated his employees! And some believed it because it was either believe it or admit your hypocrisy in PRETENDDING to believe it.
So humor is one of the first casualties in any leftist revolution. And the Left in this country feels confident enough in their long-term victory to begin implementing the suppression of humor.
