Why is there absolutely no general public comedy show that is not left-leaning?
Because rightists do not possess second-degree humor, their brain is not equipped with that. They need to keep the limited brain they have not to shit everywhere.
It's just my anecdotal observations after 5 decades on the planet, and having been an active and fundraising member of the PC party in the latter part of the Mulroney era, that conservative leaning people seem to be more inclined to have a negative, cynical and adversarial outlook on the world. And not particularly creative.
Whereas liberal types seem to be more creative, positive and forward thinking.
Again, anecdotal subjective observation but same goes for the entertainment chosen. War, crime, revenge action. movies vs comedies, romance and feel good stories overcoming adversity etc. Combat sports, hunting, fishing, football, loud powerboats, Harley's etc vs tennis, volleyball, cycling, running, sailing, gymnastics, yoga/pilates and faggity stuff like that.
It's not EVERYONE. Just my anecdotal observations.
