Its not that having your kid stand up for himself is hard to do, But nowadays, standing up for yourself can get you kicked out of school. Schools find it easier to get rid of the victims than to deal with the bullies and their parents. Been there and done that.
In school or out of school, if there was going to be a violent confrontation, the SON needed to be the one doing it, not the adult father.
Helicopter Parents just cannot let their little darlings grow up or do ANYTHING for themselves. Is it any wonder this guys little poofter 11 year old is getting picked on, if THIS is his father, and THIS is how his father deals with troubles in his son's life?
