Basically, all the stereotypes you've ever heard about these people are true. They don't know how to dress, are virgins, and usually wish they lived in an earlier era where women wore corsets and people had slaves. They often correct people's English and hate the government. You can tell someone is homeschooled because they are super defensive about it whether you have attacked them or not.
Homeschooler: (shouts to general public) "Not ALL homeschoolers are socially awkward!"
Normal person: "I didn't say anything! Who are you?"
