I would bring all of mine to a psychiatrist but it would be impossible to diagnose and treat their problems. There is no similar research or studies to refer to in the medical journals.
Pssh, I use a catch all diagnosis
"<Family Member> Is a real a--hole!"
Works pretty well.
Edit:
Sidenote: Jason Moffat really doesn't get it. He's got the creativity and mindset of a 4 year old. If we applied his arguement to other aspects of life movie theatres would be shut down because they also cater to a different target market than him. Television would also be gone, I mean, much like facebook it also spams you with commercials for shows and products not useful to you...providing you are watching TV with someone who is in grade 9 (which is the equivalent of adding someone to your friends list in grade 9, seriously if someone is spamming you and you don't like it, remove them from your friends list)
I mean, all of these "problems" come from people refusing to use a product. If you don't want people sending you spam, then don't be friends with them. I mean, if they throw spam your way and won't stop when you ask..are they really your friends anyways?
