What? Even if it were I don't see how that's at all relevant. Nor does it do anything to invalidate what I said at all. My point is just because something is dangerous does not by default make it a bad thing. Cars are dangerous as fuck, more dangerous than guns because of the sheer amount of them on the street and how utterly moronic people are. You don't see us getting rid of cars though. The same argument is perfectly valid for pit bulls. More so because we're talking about a breathing living being rather than an inanimate hunk of metal.
If you want to talk about dangerous animals then as bbbrrr_it_cold hinted at, smaller dogs actually end to be FAR more aggressive by a long shot. There's also the ones such as my ex-neighbors' mixed breed (which was mostly German Shepherd) who nearly killed me at one point for simply knocking on their front door.
My point being it needs to be handled on a case by case basis and not generalized. I really don't understand how so many left-leaning people constantly speak out about how it's bad to generalize people then go on to do the same thing with subjects that they disagree with. It's hypocritical at best.
