Perhaps if more protestants rejected contraception, their bleating on ‘socialism’ would have some bite.
What does that have to do with anything?
Other than on a few social issues (gay marriage for example) the Catholic church is basically a leftist organization. Liberal on economic issues, immigration, gun control, etc, etc, etc. What makes it even worse is most Catholics seem to ignore the RCC's teaching on the few social conservative issues they are good on, and support the populist, liberal economic crap the comes out of the Catholic church all too often. Pope Frances has gone out of his way to bemoan cutting government run social welfare programs and seems to spend an inordinate amount of time complaining about free market capitalism. It's no wonder his homeland of Argentina has been an economic basketcase, in endless defaults and fiscal failure for generations.
