Relax, my man, getting angry with a guy on the internet over a disagreement is pointless, and the insult was uncalled for. Pitbulls were bred for, amongst other things, fighting and self-defence. As such they had traits bred into them, which makes them more pre-disposed to aggression, and sometimes they don't know their own strength etc. As a guy who has had/known several pitties and crosses, my opinion is that the pure-bred pitbulls are by far more "aggressive" than those cross-bred with something else. They ***can*** be violent and aggressive, but by default, virtually no dog is going to attack you without good reason, such as being trained to do so, antagonised by unsuitable/threatening behaviour, or defending themselves. No-one is talking about killing Pitbulls besides you, OP only said they are dangerous, which is true of any animal bred for fighting or that uses a mouth full of teeth as it's primary way of interacting with the world.
