Single mothers can't raise responsible children? Yeah. Considering those kids likely had an irresponsible father who walked out on them, I guess the argument could be “they git from they daddy”. If so, why blame the momma?

Anyway! I'm sure there are statistics to prove that there are many people out there who were raised by their single mothers. They enjoy successful careers, live a happy life, and will tell the world that they are who they are because of their mothers.
