My kid's a bully and I'm proud of her for it.
Why would you be proud of a child that bullies?
I found out that she used to get bullied by the other kids, so I taught her how to stand up for herself. Now she's the one pushing them around.
It is wrong that your child used to be bullied, but it is still wrong for her to bully others. Bullying causes much harm to those who are bullied.
I don't care about that; all I care about is that my daughter can handle herself now. I gave her the confidence to stand up for herself.
It's great that she is standing up for herself now but that's completely different from being a bully. Having the ability to defend yourself is great but you don't use that ability to pick on people weaker than you. I really hope you understand and try to teach her that as well.
