I don't see how anecdotal bits can be used as proof that a generalization of many can be used to say they don't feel as strongly on social matters. There are many who even just flat out aren't aware of the Pope's social views in some regards. It's not right and I do wish they could be educated on the matter. But the article is right. His PR is very well done.
I know much about the Pope. My question is why should his lacking social views (which I also don't agree with, same as you) be used as proof that Bernie/his supporters don't have as much investment in social matters? It doesn't feel like it has much of any relation to politics at hand here and is reaching at best even if it did. It's only a quote. If the guy was running out there claiming he had endorsement when he did not that would be another matter. A nuanced matter but it would be a matter that would then make the Pope worth discussing here.
3 out of 4 of my big issues all relate to social matters. Of those 3, only one of those do I generally feel comfortable with in the hands of either of them, women's healthcare/rights. The other two I prefer Bernie.
As far as social matters go with Bernie, yes, he has a history of compromising. On quite a variety of things to be perfectly honest. Be it social and economical. The guy has a history of working across the aisle and getting things done. He fights for what he can. Is he perfect? No, of course not. No one is. Do I recognize where you are coming from? Sure. His message has had a focus on the economical. And frankly that's only one part of my support for the guy. One can prefer a candidate for more than one reason. It's generally how voters are. Of course there are one issue voters but generally speaking I like to believe voters of any candidate on the Democratic side here at least base their decision making in some varied ground.
In regards to social matters, he's frankly a bit ahead on some of those and there are two in particular which are very dear to me that make me veer towards him but I have posted on this already.
