I really don't know anyone, including Catholics, who is dead set against actual preventive birth control, that only comes up when you Progs try to use 'Birth control' as a euphemism for abortion. Even when it comes to early-stage abortion (However you want to define it, 'Morning after,' pre-heartbeat or quickening, first trimester, whatever) there are actually a pretty diverse range of opinions in Republican, Conservative, and Libertarian ranks.
