Funny you should mention Franco. Under his concordant with the Vatican, the Church recovered a large share of the liberties that had been taken away since the French Revolution, including a leading role in education. In anticlerical states, religion is banished from public education. The socialists are now engaged in an effort to take back privileges and to secularize all aspects of society.
I’m not denying any of that. However, one shouldn’t over-generalize when making statements like “THE protestants do this and THE catholics do that”. As my statement above is factually correct, I made my point.
