Kids just want to belong to something different and if they think dressing a certain way does it, that's an easy thing for them to do.

People can really be cruel .\nIt makes them think they are special .

I'm sure they do it for different personal reasons, some reasons may be "to fit in", they think it might be easier, they are having personal conflicts with their family and its a way to rebel. Some may go back to their families beliefs and heritage later - I don't know just my thoughts (dime a dozen)

Because they usually believe what they do for personal reasons and  have a different moral or value stance than you. They don't just believe what is spoon fed to them.

Why? Because some people  are here only for the purpose of starting drama. Some people have been programmed that they are right all the time, 24/7. Some people will stop at nothing to prove that they are somehow better that you, and often do not consider the consequences of their actions. Every day I am forced to watch as people degrade themselves and others trying to give themselves the satisfaction of a false superiority.
