The rare situations you cynically envision ... it would be a shame if that sort of feeling deprived people of the love, joy and companionship provided by dogs.
I would not have a Pit Bull, but you are way over the top on other dogs.
I’m not trying to be cynical but ensure people know dogs must be treated with respect and remember that many incidents DO happen. Too many on here are simply lovey-dovey without considering how many dogs DO have behavior problems (and it really doesn’t matter why). That’s not good for people, either.
My toddler son has automatically learned to love dogs - my German Shepherd has been watching him since he was born - but I also must teach him respect for them (including her) so he doesn’t run afoul of a lesser dog. Early on I fear I let him do too much with her, and he thinks he can do almost anything with any dog, which I have to correct, because it just isn’t the case much of the time. As he’s getting older he’s learning a bit more how to approach them.
I love dogs, and most are fine with strangers even, especially treated with respect (I take my dog for a bath every week and get to pet many dogs at the groomer’s). But I have no illusions that they’ll always be trustworthy. And I tire of the cat-hatred that goes on, too.
