Plus ça change, plus c’est la même chose; or, the more things change, the more they remain the same.
In 1960, Protestant Americans were afraid that a Kennedy election would mean that the Pope would have a say in American politics.
In 2014, with the Pope having been anointed (inaccurately) as a pro-Choice, pro-gay marriage savior, Progressive Americans are worried that American Catholics are giving him too little say in American politics.
The result is that now, as in 1960, we’re once again seeing explicit anti-Catholic bias. [Link error corrected.]
UPDATE: I forgot to add that today’s Progressives also love the Pope because they think he supports a redistributive economy (and they might be right about that, even though they’re wrong about his views on abortion and gay marriage).
