copyright laws

there's gonna be three dance teams auditioning for the school performance next tuesday..
and commasow cliQue is one of them..

and there's also another group with 11 people and yet another one with about 20 people..

the thing is..
that group with about 20 people keeps copying everything commasow and the other team does..
our steps..
wadever stuff i try from the view of flexibility..
like bridges, splits, box steps, push steps and many many many many more..

i mean..
they have almost 20 people in their group..
dont tell me that they dont have enough brains of their own to think of their own steps and ideas..
they totally have no originality at all!!
always copying..
and when we confront them they will say that their not copying and that those steps are theirs..
this isn't fair..
dont they have any guilt?? when they get through auditions but not with their own steps??
do they even have any feelings??
do they know how much time and work i put in to get those steps??

i want copyright laws on my dance steps!!

it wouldnt help if we complained to the teacher in charge..
they are like automatically in cause they have alot of members and teachers like that..
and if any of them view this blog..
i juz wanna tell them "please STOP copying!!!!!!"

but in the end it's still about having fun..
but how do we have fun if we're pressured by them taking our steps??
