I know what you and her both are going through. I am happy that my mom let me choose my religion as well do to the fact that both of my parents were in childrens homes that had Jesus and god throwen at them 24/7. corptal punshment was part of this church school as well. I went to highschool waring small pentacles that were not massive like most crosses I see. Advice is that you need to be carefull with this subject and school. my freshman year I was beat up in the girls locker room and had my cloths taken from me and torn up. You know what the funny thing is I never wore black. I looked like any other student. The principle told my parents maby I deserved it as punishment from god.
witches voice is a great place to get support for stuff like that concerning schools.
