It you say that Polish catholicism is fundamentalism then I would be a extremist too since I am also a quite religious person. On the other hand i.e. capital punishment is something that is simply not accepted in western Europe anymore. Countries that are doing that are seen as barbarians by the broad western European public (Our American friends will crucify me for this statement, but it is the truth). Therefore countries that have such a law practice simply do not fit into the EU or other European clubs.
There are some points that would split up our ways if your gouvernment will push its whole agenda through.
