I get the mindset for these people. Their dog is probably never going to go nuts and maul someone, the vast majority will never go nuts and maul someone, it's your big good boi! Its not the animals fault it literally has been bred to be a killer, you didnt train it like that, thats not the environment it lives in... and yeah thats all true but when it goes wrong it goes spectacularly wrong and people die.
Its like people who have pet bears or big cats, like... yeah all the positives and all but its absolutely equipped to kill the fuck out of you should the mood strike it.
