Then why not post about EACH AND EVERY instance of bullying done by 5th graders? I'm pretty sure 5th graders are bullying kids for every mundane thing.
When a society has to fish for reasons to hate outsiders, as you have admitted the issue is BIG in Australia then you're fessing up by making a mountain out of a molehill. The kids should go to detention, they should be punished (as much as 10 year olds should be punished), but you posting 2 months old news and posting a very very lame topic about Australia in a Pakistani Defence forum, all points to the intrinsic xenophobia (not to mention the bouts of violence being experienced nationwide by Indian kids in general for being Indian) of yours and Australia by extension.
Please in the future, post topics concerning Pakistan only!
