I know, I happen to be an EU citizen myself. I was simply saying that a global "all EU countries don't have those cons listed" to the poster I quoted is wrong. But thanks for the smarminess.
There's no "state religion", yes, but depending on the country, it very much permeates law and civil life in some. Shops close on Sunday in Italy, Austria, Southern Germany (possibly all of Germany), France, Hungary and are going to be doing that soon in Poland. Not sure if there's others, but I know those for sure. Also Switzerland, albeit not EU. All of those countries are absolutely a Catholic dominance, what with a majority of people being Catholic (60+%), except in Hungary where it's around 40%. And of course, Northern Germany is Protestant-dominated rather than Catholic.
There are exceptions to this both in the form of countries (e.g. Spain does not have bans on Sunday shopping iirc), and there are exceptions to those bans in the aforementioned countries as well (e.g. in Austria, shops are allowed to be open on Sundays if they are in train stations or airports, and restaurants/bars are allowed to be open every day).
Yes, most of the people in these countries are only Catholic on paper, but saying there's no Catholic dominance is wrong. There's also a fact that Catholicism has imprinted many values, opinions and approaches to yes, even law, upon the countries it is the majority religion, and is very much something that conservative and right wing parties, which are on the rise in a lot of EU countries are priding themselves in holding up high.
A country can be secular officially but still have many religious aspects to it, even if the members of the religion aren't super pieous.
