Having read the article, it seems that they use "wars of religion" as a euphemism for our "culture wars."
That said, reaction to European "wars of religion" seems to have destroyed religion there.
Yes, the triumph of Secularism, i.e. of decadence, in Europe has destroyed religion there and will destroy Europe itself if present trends continue.
This decadence has infected Europe like the Black Plague and threatens to be even more devastating and catastrophic. Europe recovered from the plague. It will probably be destroyed by this decadence, unless Europeans wake up and come to their senses.
Americans hope and pray that Europeans will save themselves before it's too late, but so far it appears that prayers to St. Jude are the best bet, and apparantly most Europeans don't believe in prayer or saints (or anything else).
That and the state churches. Christianity thrives amidst competition. That doesn't mean that the government shouldn't enforce reasonable things like prayer in schools and the ten commandments on public buildings, because ALL religion is under some rubric (either Christianity, Judaism, Islam, or atheism). But the more competition you allow, the more vibrant religious faith is, according to numerous studies.
The wars are not wars of religion, they are wars that are fought because of the values that our country believes are important. Those values came from our religious background as a nation.
