Don't get me started about people who own pitbulls, as I have some unpleasant things to say.
First, if you're reading this and you own a pitbull, it's likely this post will offend you though I hope it doesn't - you might be the exception to the rule, you might be a perfectly normal, dignified, responsible person who just happens to love pitbulls for some reason and you conduct yourself in a perfectly responsible way.
But for the most part, you can take the pitbull out of the ghetto but you can't take the ghetto out of the pitbull. 99.9% of pitbull owners are irresponsible, low people who (rightfully) assess their dog as a dangerous weapon that's satisfying to know one owns. Tragic accidents involving pitbulls or pitbull-adjacent dogs are real, and terrifying, and inevitably accompanied by the galling-ly stupid comment from the owner "But he had never done anything like that before!" [as they pick up the pieces of what's left of grandma].
If there was a weapon that could run around the neighborhood firing shots by itself, I would not own or let that weapon loose. Apply the same logic to dogs - don't be stupid and own something that's essentially an auto-firing weapon that can hurt people.
And the main thing? do NOT be offended when your pitbull approaches me and, having no other recourse, I pepper spray it, because I have before and would again if needed. do not yell "He's friendly". I don't care how friendly he is. If he looks like he's about to make contact wiht me and it's a strong dog I don't personally know, it's getting engaged.
