Your comment is misogynistic. Stop blaming single mothers for all the world's ills. Bullies have been around forever. Even other primate species have problems with bullies. Bullies existed well before single mothers became normalized. Being a single mother has nothing to do with bullies. For the record, every bully I ever knew had a domineering, authoritarian parent whether they lived at home or not. That's much more likely the cause of bullies. Kids become what you teach them. If you bully them, they learn to bully.
