A cultural Iron Curtain now very much divides the two halves of the EU. To the west, are the more progressive, ethnically diverse and secular states of western Europe. To the east, are the more traditionalist, more homogenous and largely re-Christianising former communist states. Slightly shocking perhaps to some then that the conservative and historically Catholic Czech Republic (Czechia) is on the verge of legalising same-sex marriage, a move which would make the country the first in central and east Europe to do so.
