That's correct,dear friend,and separation of church and state is against Catholic teaching
The syllabus of errors covers much of this and condemned the following as grave error against God ...

Pope Pius was writing from the point of view that these cover Christian societies and also that all nations ought to be Christian ones. The fact here is that Italy is not. You are mixing two things into one here; what should be done with the current situation w.r.t. religious practices in public institutions, and what should be done w.r.t making those public institutions into Christian ones.
Boston College is a Catholic university; I not only approve of, but expect crucifixes on the walls of the classrooms. The problem is that in a strictly secular institution, who approves religious symbols and who pays for their purchase, installation and upkeep? Shall the crucifix occupy the space beside a swastika, a hammer and sickle, a moon and scimitar, an icon of Tom Cruise jumping on Oprah's couch, and a rainbow GLBT&OO? If not, then what separates them and makes one acceptable and the other not? Your own personal whim? That is no better than the sultans of self-interpretation of Scripture.
The reason why Saudi Arabia does not and cannot be forced by any world government to display the Star of David anywhere is that their state is a Muslim one and therefore a champion of Islam and not a champion of Judaism. They do not have to permit Jewish religious practice in their nation if they so choose. That is why the state institutions (also Muslim) do not have to purchase Stars of David and display them or allow others to do so. You want crucifixes on classroom walls? Create your own school and put them there, or else change the laws of the country and each state of the Union to make the US into a Christian nation.
No. This is a parochially American view of the law, infected by the Pavlovian reflex ACLU infected us with.
Italy may not be a Catholic country constitutionally, but it is a predominantly Catholic country. This is all we need to know. Where do these cretins in the Hague (or is it Brussels) got their power to dictate what is or is not to happen in Italy?
Those who don’t want to look at a crucifux are free to have a privete school without one, are they not?
