"Western Europe" nationalism is curbed because nationalism is a threat to the neoliberal EU project which is itself too big too fail. Looking at the issues of Spain/Italy/Greece you'll see specially how Greece was forced to accept the German led negotiation(the Troika) of their deals or suffer severe consequences. You can read that Varoufakis writings where he basically admit the "socialist" option(or really any anti-imperialist arrangement) like leaving the EU, abandoning the Euro, defaulting, becoming socialist was not an option period.
It is not about "liberals" fighting nationalism out of good will lol as much as neoliberals having to maintain a heavy grip on the nations part of/close to the imperial core. Is that something to applaud them for? I mean this is a thread for lib takes so maybe. But from an actual leftist point of view not at all.
Then you compare that to the former USSR countries and you can see the clear differences. While the entire western capitalist countries conspired with and supported nationalist anti-USSR/right wing movements in order to de-stabilize the region, the same policy can't be applied back at home. Germans for example have no reason to be extremely nationalist when Germany is already at the heart and control of the EU. The same goes for France. Both are changing though e.g the migrant crisis.
But as I said as soon as you look at the edges like the UK/Spain/Greece/Italy you'll see neoliberalism is not able to contain this threat any better than other countries.
Can we please not quote the head of a feudal slave society Tibet until 1951, I don't think the Dalai Lama was very interested in the inner workings of Marxism while he enjoyed the company of his serfs.
If you want to rehabilitate the current Pope because he says nice things that is ok, do it at your own risk of credibility. Words are cheap, actions are what matters and the Catholic Church is the definition of inaction and criminal activity.
Don't quote mine the Bible, it is one of the most hateful books in existence. A handful of vaguely leftist statements don't erase nice little gems like this "how you get to keep the wife and children of male slaves for yourself". Exodus like the rest Old Testament is a human disgrace.
I recommend you go through the Skeptics Annotated Bible. The Old and New testament each have their own flaws are have more than enough bigotry in either one.
I am very supportive of Christian and other religious socialists/communists in any community, and I believe we can continue to support any religious person who wants to become or is already a leftist and a socialist by upholding our own human decency principles and not trying to rehabilitate religions with scriptures full of hate crimes and bigotry.
God may be a communist, he certainly almost never acted like one.
