Is there anything specific about bsl that you object to, because it varies from a country to another? For exemple, in my country you are required, if you own a dog belonging to a breed deemed dangerous, to microchip our dog and always have a leash a muzzle when you take them out. There are a few breeds that require the own be over 18 and not committed any crimes involving physical violence. That's pretty much it. I don't find it that bad, considering that, while I could defend myself against a bichon or even a lab, I don't know if that were the case with a 50+ kg mastiff or Rottweiler or something similar. And while my dog is sweet and well behaved, that is not the case with every other dog. Of course, it's usual the idiots that don't educate their dogs that allow them to run wild. Anyway, as marke said, you can't protect the society from stupid people, so you try to limit the ways they manifest their stupidity.
And yes, I would love to be able to take my very well mannered Cane Corso for a walk, without being nipped and barked at by stupid little critters,
