There's a lot of ground between constantly harping on the same target over and over every single episode and saying they're just not going to bother trying at all because it's somehow too hard. You'd think people who make a show where the philosophical truth is always found somewhere in the middle would understand this.
EDIT:
Let me elaborate. That is the reason they are cowards. Because they spent twenty years building their comedy on the easy joke of "ha ha, you care about something". Of any intensely held belief being an extreme. Of every side being wrong. They sat on the fence and threw rocks because that was the easy thing to do.
And now, when there is one side very clearly worse than the other? A relevant topic in which that style of comedy can no longer seem prescient or informed or in any way true enough to generate humor? They tuck tail and they run. Because, as they themselves say, it is too hard.
Because they are cowards. And they only know one joke.
The emperors are naked.
