That is absolutely false. Every bit of it.
No it's not. You're just ignorant. You're operating on myth and folklore and nothing more. Nothing of your allegations is supported by fact or any sliver of science.
You have no comprehension of selective breeding. You believe the difference in the size of chihuaha and a Great Dane is coincidence.
What a ridiculously stupid thing to say. First, never said anything about the size difference between small and large dogs being a coincidence. That's a straw man argument, and a flagrantly transparent one at that. Second, I understand selective breeding quite well, and I am significantly better versed in how selective breeding has been utilized in the engineering of the APBT than you. I've even given a brief explanation of how selective breeding has been applied to the breed, while you have nothing but your folklore claims and a stubborn, dogmatic belief.
What's even more ironic, is that you invoke the fact that selective breeding is used to engineer desired traits yet you don't even bother to consider for one moment how selective breeding is actually engineering the APBT today. A hundred years worth of selective breeding is an extremely long time that can yield substantially different results than what was originally intended. Entire new breeds can be developed in that time. So even if it
had been true that APBTs were originally bred for aggression, or your BS idea that they were bred to "bite and hold," it would have no bearing on the APBT of the 21st century.
I really marvel at liberals who are anti-pit bull. The sheer ignorance is amazing. Liberals like to claim to be so anti-racist, but the exactly same ignorance and blind hatred that generates racism is the ignorance and blind hatred that generates anti-pit bull beliefs and feelings.
