This picture of John Colby says you're wrong.

Most men at that time used to dress pretty classy even poor ones..
especially for a photo portrait.But Colby was known among old-schoolers as a
peddler.Having a game pit is a huge responsibility, even a cur pitbull should NOT be available on the hands of the public.
Reason is that the oldschoolers knew the consequences, not only against other animals but time to time Manbiters pitbulls existed, no matter how you raised.
Gr.champion Zebo, Gr.ch Virgil, Gr.ch Angus were notorious man-biters.. and imagine these dogs on the hands of person with zero knowledge about pitbulls? let alone dogs?!! they'd even bite you if you didn't release them when they saw another dog/cat/person..
