Sounds like lots of good parenting. I got in a few fights Dad had my back and I knew it. Amazing how things change for the better when your classmates watch you tear into a bully. I raised my boys the same way. Three kids 11 school districts never had a problem at any of them.
I think the fact that they were confident and were top end wrestlers deterred a lot of kids from crossing them. They were tough and in shape, average size and could prolly put any kid they wanted to head first in a garbage can.
