You clearly have anger issues...
That, and an inability to recall the studies and statistics many of us have posted, claiming that all we have posted are "salacious news articles". Worse yet, you clearly cannot even understand the very paper you posted as the centerpiece of your argument.
The authors very much acknowledge pit bulls to be far and away the breed most guilty of attacks leading to serious injury or death. In every case in which they do so, they are careful to provide a footnote to the referenced study(s). Where the paper falls apart, however, is where they try to explain it all away with statements that contain "may". These statements are glaringly different, in that they are not supported with a footnote to any kind of relevant study. As such, they are clearly no more than the authors' opinions. As much as this paper dwells on pit bulls, offering unsupported opinion in its attempt to say it isn't the breed, it's obviously written by some sort of pit bull apologists. No wonder you like it.
So, yeah, here you are, backed into a corner and lashing out with childish insults. You keep repeating the same false information; it keeps getting debunked by the rest of us. Must be frustrating, but it's no reason to devolve into childish insults.
Here is something for you to chew on. The authoritative source on dog bites in the U.S.:

From the above link:
31 U.S. dog bite-related fatalities occurred in 2016. Despite being regulated in Military Housing areas and over 900 U.S. cities, pit bulls contributed to 71% (22) of these deaths. Pit bulls make up about 6% of the total U.S. dog population.3
Here is a chart showing the above data graphically:
This pie chart, from the site above, is pretty damning. 64% of fatal dog attacks in the U.S. over a 12 year period are attributed to pit bulls:

I have posted the above links in the past. I thought I would repost, thereby giving you another chance to ignore them and lash out at me with childish insults instead. Face it - your position is unsupportable. This is very much a breed-specific problem.
