I kind of understand where
_Tonks_ is coming from even if she may seem to have a rotten attitude about it...
I think we should keep in mind there is an ideal side and a practical side. I don't think anyone is denying that the bullies are bad for doing this, but it is hard to prevent bullying, and easy to tell the kid to stop bringing the bag. It might not have been the only reason he was bullied(I don't know the whole story), but I think it's understandable why the administration would think it would end the bullying. kd24's post on the first page pretty much sums it up so I'm not going to go on about that. There's also another thread about bullying in general from back in August:

In middle school, I was bullied because I was a fan of Bionicle. It ended when I just laid low and eventually people either forgot about it or just got bored and it never came up again. A lot of people say that we should try to stop the bullies rather than making the victims less of a target. I agree with the sentiment, but we should remember that it is
hard to change people. It's not as if they would realize it was wrong and stop just because I (or a teacher) told them so, especially when we are young kids and don't know anything. Does that make them right for bullying me? Of course it doesn't, but it was the only practical way to (somewhat) mend the issue.
Tonks' comparison about the wheelchair also makes sense to me...she was forced to go around in a wheelchair but he
chooses to bring the bag. Again, the bullies are obviously morally wrong for bullying, and I'm not sure if the bag was the only issue, but if the kid knew he couldn't bring the bag without getting harassed for it, and knew he wouldn't be able to take the mean comments, then continuing to bring it at that point is just plain stubbornness. No longer bringing it is the practical solution in this case, even if it means the bad guys win. Tonks did not have that ability...I hope it is understandable why "don't go out where people are ever" is not a good solution.
I hope I don't sound like I'm victim blaming...I don't think the kid is weak or stupid, like everyone else said, he is just a kid, and it is certainly the bullies' fault. But I hope you don't dismiss Tonks' actual points just because she has a bad attitude. In a perfect world we'd get rid of all the bullies, but there just isn't really a practical way to do that yet.
