I liked this article:
It’s not a good time to be an American XL Bully. The breed, an extra-large pitbull variant, has been blamed for a threefold rise in fatal dog attacks in the UK; after a series of high-profile maulings, bullies have today been added to the list of breeds restricted under the Dangerous Dogs Act...

Especially this part:
Sadly with genetics people can't separate 'individuals' from 'groups'. You make a comment about averages across groups... people see they belong to that group and don't fit the average and say "it's obviously rubbish because I'm <x> and it doesn't apply to me!". That can be true of course.
Governments have to legislate for groups. And while it's true that any individual dog can be the sweetest thing, when you take a breed of dog, and look at them as a group, you can see differences. Certain breeds, are, as a group, more dangerous than others, and that is why they should be banned, like the Bully XL.
