I want to talk about the "tough guy dad who is abnormally over protective of their daughter stereotype". Yes to start off with I get it's a joke, but in my opinion it is a really old and over played joke. It has become a bit of a pet peeve of mine, and I believe I've written about it before. Why live up to a stereotype? Yes some of these are funny and make me laugh, but most of them are simply keeping an old stereotype going. You want your kids safe, but to talk about it seriously and not just the jokes, you should be teaching them how to choose a safe partner, someone who won't hurt them, more than just threats, but wisdom too. You end up scaring away the good suitors more than the bad. You're left with the ones who are not afraid of you, not the ones who respect you. You want your children to come to you if there's a problem instead of worrying you will over-react. It's fine to be a jokester, but also some times it's good to take things serious and be real. Don't live up to stereotypes, fight them.
This comes from a time where women were seen as "possessions", owned by their family, unable to make decisions of their own, which is wrong on many levels. This also leads to the brother/sister thing with the over-protective sibling. Why get angry at your friend for dating your sister unless you have shitty friends? It's okay for them to hurt others but not too close to home? What kind of person are you that you wouldn't let any of your friends date your sister? Says something about yourself as well that the people you surround yourself with can't be trusted with family.
