You don’t have to tell people that sex is great, or that pizza is delicious. It’s self-evident.
That could perhaps be an episode in a new version of Sliders:
The Sliders find themselves on an Earth where in not just that Earth’s version of the US, it has for generations been the Order For The Day that sex is NOT great! It is a chore that married couples are to engage in for reproductive purposes only, taking no pleasure in it. Anyone found to have engaged in sex that was non-marital or/and non-reproductive, like same-sex or/and just for pleasure, is punished with being put on a sex drive repressing drug that is highly addictive.
Likewise, ever since pizza was introduced, it has been the law that it can only be made and eaten at state licensed pizza restaurants. Which anyone is allowed to visit only four times a month, maximum. Admitting to liking pizza is officially regarded as decadent.
But a pair of BLM-like movements saying Sex Lives Matter and Pizza Is Delicious is on the rise. There have been many clashes in the streets between SLM and PID protesters and riot police, unarmed SLM and PID members have been shot dead by cops who fired without warning.
