Banning religious garb in schools is already a restriction on religious freedom, so it's just a question of where would be best to draw the line. I'm fine with some restrictions, not with others.
In the UK we allow both private religious schools and home education, and religious garb in state schools. This has pros and cons.
In France, they allow private religious schools but ban religious garb in state schools. This has different pros and cons.
I could easily imagine a state which banned private religious and home education (isn't home ed already banned in Germany? I may be recalling that wrong) and also banned religious garb in state schools, same as I can imagine a state banning certain harmful religious practices, like FGM, infant male circumcision, halal/kosher meat, animal sacrifice, underage marriage, etc.
I think the UK liberal approach certainly the easiest, but it does lead to many unpleasant results. Perhaps we should slowly restrict religious harmful practices more, and separate church and state more as well. It's difficult because restrictions of religion have often led to terrible persecution in the past and that's not good either. Getting the balance right is hard.
