I'm not racist against any religion, all have their pros and cons, but demanding that you have to wear a scarf on your head is just a load of rubbish. If you choose to, great, if not, it's not the end of the world. Your parents need to remove the stick from their arses and realise times are changing.
There are more ways than one to show your faith, don't be cornered into one because your parents are back asswards.
