One of my main reasons for homeschooling my son is my fear of bullying and the crappy, artificial social environment in schools. I don't want him to be teased, or worry about if he's wearing the right clothes, or feel like he has to live up to the "cool" kids' expectations, etc.
But won't all this happen to him anyway, among his peers outside of school? Right now he's 4 years old, and when he hangs out with his homeschooled friends, he is often excluded from play by the other (usually older) kids. One of the boys he likes the most is always mean to him, excluding him, hitting him, telling him he can't play unless he follows this boy's rules.
Obviously he needs to interact with other kids, and sometimes they are going to bully him, so is he really going to be any better off by being homeschooled?
