Pit bull temperment.

I'm in search of a good post, article or links to the reality of pit bull temperment. I have two bull mixes & I've done a lot of research on the fact of possible DA stemming from heritage.. & prey drive due to pit bulls ultimately being terriers. It drives me absolutely crazy when people who own pits & "advocate" for them make comments sarcastically about their "vicious" dogs.. This & that.. But the truth of the matter, as we all know, is that these dogs were bred & used for fighting for decades. People overlook this & are careless with multiple pit households, etc. Something I learned on this forum almost a year ago, is that you never leave 2 bull breeds unattended & you always keep break sticks on hand when owning multiple pit bulls. If anyone can point me in the right direction where I can find good information on any of this, I would greatly appreciate it! Thank you in advance.
