Think alot of iranian girls are the most racist,backstabbing and untrustworthy people you can meet?

That's like saying "omygosh you guys, I HATE all men named Mike. I mean they are so freaking annoying and rude. ALL of them. If you're name is Mike, you are most definetly a loser". It's obviously not true. You've probably just run in to the wrong ones. I mean, maybe their culture teaches them to be that way...but you can't judge EVERY Iranian woman on what you've encountered with a few.
