You a shut in? I ask because you obviously don't get out much. These dogs have been around since out country was first immigrated to. Teddy Rosevelt owned an APBT, took it with him all the time, you know to bite foriegn dignitaries and such when it was out of control.
And as I live in Manhattan, I've seen a lot of them.
So living in Manhattan makes you what...the all seeing, all knowing, judge of something like 4 million dogs? You sir, are high.
So you with the one possibly-non-deranged pit bull in existence in your backyard can huff and puff till you turn purple, but it doesn't change the truth.
LOL, the truth is that more people are bitten by Jack Russel Terriers than by Pit Bulls, hell, more people are bitten by humans than by all dog breeds combined.
