Vlasta & Michaela,
well, it's not a scientific study but was only a discussion in this forum about the question, why there exist so called LGBTQ-free zones in Poland whereas in Czecia people seem to be very tolernat in this case. I think, that has not that much to to with catholicism in general and atheism, but may be with the special polish and czec contexts. I think we should ask about the role of Roman-Catholic Church for Polish national consciousnes and Hussism in the Czec one. The Polish had to resist against Prussian (Protestant) and Russian (Orthodox) supremacy. Only the Austrian aoccupying force was also Roman-Catholic. In Czecia this Roman-Catholic Austrians where the occupyers, and Hussims was the national religion against it. After the II. WW both countries where occupyed by atheist USSR. In Poland catholicism remained beeing the national Polish religion against the occupyer, whereas Hussims did not take this role in Czecia. I don't know, why the development went in both countries in such different ways. But knowadays a strong part of the Polish Catholics are similar conservative or reactionary like some parts of protestantism in the US: Against modernism, against the EU, against any foreign influence. Might be you can help me to understand it.
Your photos are really very beautyful! Do you remember, which evangelic(al) church it exactly was: Lutheran, Reformed or something else? In Germany some parts of the Evanglic Church (Evangelische Landeskirchen) are very liberal, whereas many envangelical churches (evangelikale Freikirchen) are more fundamentalistic.
