The Republican party has become a full-fledged anti-sex movement.

True, but the real issue is that the right and the left in the US are both anti-sex now, they just manifest this tendency in somewhat different ways. The right’s variant is worse and more authoritarian, because of course it is. But the left is also quite anti-sex with a side of anti-men now, and that assists the right in achieving their goals as there is so little pushback from the left these days on these topics.

The prudes are winning, in other words. Both sides of the aisle are guilty, though not equally so.
