Much as I disagree with numerous Catholic doctrines, I applaud them for not caving into what's "popular" and standing for what's right on this issue.
The Catholic Church is not a political lobbying group. Hell, they can have their position and mention it and still Stand For What's Right
TM, but this is not that.
What they're doing here is this: they have money they could use to clothe the poor, feed the hungry, heal the sick (including those with addiction problems), etc.--but no, they're using it to fund laws that put people in jail (often breaking families apart) for non-violent "crimes," make marijuana usage more dangerous due to lack of regulation, and don't do anything to actually help the serious problem of addiction.
You shouldn't applaud, you should be appalled.
(Also ftr "wrong side of history" is a ridiculously annoying cliche. I hope "history" decides against using it one of these days.)
