The US right-wing obsession with abortion is a relatively modern phenomenon, and was fairly deliberately cultivated. In many countries it isn’t really a left-right thing at all (except maybe amongst the extreme far-right, but you’re really talking the fringes). It’s not because it’s fun; it’s because it has been a very effective wedge issue for them.

It is fun, though. That's the whole point of a wedge issue. You invent some made up problem and then fight for it in an effort to feel the glory of superiority. It is effectively a sport.
