even with this personal evidence, you get defenders downvoting the story - not because it doesn't add to the discussion, buy because it doesn't suit their narrative.
Not really commenting on the claims made in this argument, but this is anecdotal evidence. Meaning that someone who claims all pitbulls are sweet and docile because of their personal experience is just as valid of an argument as someone saying all pitbulls are bad because of their personal experience.
I don't really care about pitbulls one way or the other, but I find it worrying that a lot of the times the debates against the breed follow similar argument structures to those utilized by racist pulling up FBI crime stats about black people.
