Except the article do-sent metinon anything about dogs being bread fof fighting. (as I have read it before).

Unles you are going to somehow present evidence that no breed of dog can have certain characteristics of personality enhanced in a majority. It is no more invalid then saying boys dont like trucks, Because sizeable % do not. it is still a fair genraisation.

And given we are discussing a breed of dog sold to appeal to a specific class of buyer. The points are rather invalid.
