Minor local issue and musings: a 'concerned' parent complained to the Viennese school council because the school his son attends segregates classes based on religion. There's one class with catholics and orthodox christians, and one class with all other relgious minorities and those who are non-denominational.
I myself am Lutheran, which here is a religious minority (behind muslims and orthodox christians), and indeed, I too, have experienced segregation: I was always in classes that had all other Luterhans if there were any, as well as other religious minorities. I fully understand that we cannot be allowed to fill the catholics' heads with heretical nonsense, that always seemed fair. Imagine, our priests are allowed to marry, if something were to happen to the catholic celibacy...
Well, all joking aside, as I am Luterhan in name only, the real reason for the segretation is not that the schools are racist, but it is simply a matter of expedience, and one where the fault lies largely with the untoward influence the catholic church still holds over politics, particularily over our conservative party (who formerly called themselves 'christian-social' party before switching their moniker to 'people's' party).
Since every school has to educate its students about the invisible sky fairies they believe in, or at least nominally should believe in, and most students are catholics, schools generally have a dedicated teacher at hand to tell them about the catholic invisible sky fairy. Teachers of the muslims, orthodox and lutheran invisible sky fairy however, have to teach at several schools, and it is much easier to find free time slots when the minorities are all in the same class, because otherwise one runs into an issue that I also experienced, namely that we'd start a day at school later, because the first class was about the catholic sky fairy, and our sky fairy classes were after everyone else went home, or worse, sometime in the afternoon.
So, it was coming home from school, doing homework, and going back to school to learn about our special sky fairy. Except... they're apparently all the same invisible sky fairy anyway, making this even sillier than I ever imagined it to be when I was a lot younger.
Clearly, there's one ideal solution to this issue: remove religion from the curriculum and replace it with ethics, and change the curriculum to include knowledge about a broad range of religions, rather than just one. Alas, such left-wing commie heresy will never happen. The complaints would be endless, from catholics, muslims and orthodox christians alike. So, sky fairy segreation it shall be, forevermore.
