Unfortunately, that's not only not true, but it's so not true I can't even provide evidence without the danger of taking this thread into lockable territory.
I will say that I envy you for missing out on some of the internet's greatest hits of the last few years. Not sure how you missed it, but I can assure you that you are better off. I'll just post this quote, from the New York Times:
"Meanwhile comedians advertise their racist jokes as bold challenges to the tyranny of political correctness, and brand their bigotry as boundary-pushing, taboo-busting bravery. The anti-authoritarian spirit of comedy that flows through Lubitsch and Chaplin to Brooks and his heirs is twisted away from its humanist roots.
At the same time, authoritarian leaders prove impervious to satire. Laughing at how stupid, pompous or corrupt they are doesn’t seem to break the spell of their power. The joke may be on those who persist in believing otherwise. If it were revived today, “Springtime for Hitler” might wind up being a hit for the wrong reasons. Or it might flop because those old Hitler jokes aren’t as funny as they used to be.
I don’t blame Max Bialystock. I find myself envying his misguided faith in the high-minded good taste of the public, even as I cherish Mel Brooks’s belief in our irrepressible vulgarity. Part of me looks back fondly on the days when fascism seemed like history’s dumbest joke. And part of me thinks we’d all have been better off if the opening-night audience at “Springtime for Hitler” had stormed out of the theater in a rage, leaving Max and Leo to make their way safely to Brazil."
