Just because someone else is a asshole doesn't mean you have to be a asshole aswell.
Treat others as you want others to treat u :P

And i can promise you, if non-japanese people keep leeching off japanese network (which isn't meant for you or me like it or not) they will block non japanese ip or find another way of keeping us out. So no matter what leeching wont help you.

And yes most japanese people are very racist but thats not a excuse for acting like a jerk.
