What do you think of Pit Bulls? I know they are common, but they sort of scare me
Where I live they are very common, however it is a nature vs nurture type of thing. I've met some that are scary, some that are total sweethearts!
Yeah, it is tough, because they were developed as fighting dogs, and that is been breed into their nature, but they can still be sweet
Well I actually read recently that they were originally called "nanny" dogs and they were responsible with children, and because of their build it resulted in them being exploited for that. 
I had never heard that, I know that they are unfortunately used for illegal dog fighting underground still, that hurts my heart
