I don't know the validity of the report of Germany banning pork but obviously if they did do that, for religious reasons, I would be very much against it.
Doesn't matter whether they do it based on Islam or based on the Bible verse that forbids it.
The lucky thing about being in America is we have a separation of Church and State that shields us from having religious laws forced upon us and also protects churches from government control so both religion and government are more free.
No I would not tolerate someone thinking that I have to follow their religion's rules when I am a non-member.
As for prayers, again I doubt that this actually is the case. The only way I would be in favor of religion being taught in schools is if the schools taught a bunch of different religions and rather than saying one of them must be correct they just provided the students with the facts. They could teach children: this is what this group of people believe, these are some variations of those beliefs, this is the mythology or "holy" text that belief is based on - just the facts with no indoctrination.
For example most kids learn about the ancient Greek and ancient Egyptian gods in school but schools aren't trying to force kids to pray to Zeus. Something like that is okay as long as it is taught without any attempt to make one religion out to be better than the others.
But obviously as an atheist I don't think anyone should ever be forced to pray or even instructed to do so by an authority figure. Doesn't make a difference to me if it's to Allah, Yahweh, Zeus or the flying spaghetti monster, kids should be free to pursue their own religious identities not be indoctrinated.
