I'm not part of the fetish, but I do know the answer.
Pit bulls kill 12-15 human beings per year in the USA. Most of the dead are very young or very old.
Since 1982, pit bulls have killed more than 500 human beings.
Since 1982, mass shooters with semi-automatic rifles have killed 300 humans, and that includes the 58 people murdered by the Las Vegas shooter about six months ago.
Interesting that someone would call these postings a “fetish”.
I believe that your numbers are a bit out of date, on the low side. I thought that the number of deaths in the US was 29 last year.
Update: I was wrong. I was low, too. The information is below.
Pit bulls killed 40 people in 2017, 39 in the U.S. and one in Canada, a total of 12 more people than were killed by pit bulls in 2016 and five more than the previous record of 34 killed in 2015.

I am trying to follow the money.
Why is anyone concerned about a vicious pit bull. What about the little rat terrier?
