I agree Islam is more than “just a religion.” Though it’s fair to point out so was Christianity up to about 500 years ago.
But that it is “more than a religion” does not mean it is not a religion. It meets every logical, linguistic and legal definition I’ve ever seen.
To exclude it from legally be a religion would require redefinitions of the term, and then giving some government agency the authority to decided which groups do and do not fit the definition.
This would be a really, really bad idea.
Christianity was all encompassing in Europe until the last 200-300 years. The move away from the faith has been more pronounced in Catholic countries. The 16th and 17th centuries saw protestant , particularly calvinist, countries followed various confessions (westminster, heidelberg, begic etc) in and out of government. The biggest break, unfortunately, occurred in the United States with our Godless Constitution. Followed by France with their godless French Revolution (France arguably fell away permanently at the St. Batholomew’s Day Massacre) From there fell the rest of Europe which culminated in the godless World Wars and modern secularism which recognizes no God and has no concept of the danger of Islam.
