Which were still turbulent years just 20 years from cold war, you forgot to say that. Also it was tougher for mixed Native American and Irish in late 19th century that it was for black people in 1940/50s. You forgot that Dempsey also worked on a farm like a mule and became a hobo at young age without food or any place to sleep unlike Sonny who went to live with his mom. Liston had a place to sleep and eat while Dempsey hadn't, he fought for food and place to sleep while Liston was a leg breaker and a thief that used to rob people. Dempsey fought to survive unlike Liston.
You are,as usual, posting absolute rubbish.There is no way that Jack Dempsey could have been identified as anything but a typical American,either in speech or appearance. Did Jack Dempsey's father whip him so severely that his back was permenantly scarred ? No. Your argument about life being tougher for mixed Native and Irish folks than for black people in the periods that you mentioned is not only dubious but completely academic.I repeat, there is no way that Dempsey would have been identified as anything but an all-American boy. Do you really think that Liston,at the age of only thirteen years old ,running away to escape his brutal father really had an easier life than Dempsey who elected to leave his family home as a young adult ?
I'm afraid your insistence that Dempsey didn't learn the art of self-defence while he was having his unofficial fights shows your rank stupidity.
LOL ! You really do have this convenient loss of memory.Jack Dempsey drew 2 fights and lost one fight against men who would make Marty Marshall look like an all-time great by comparison. This has been pointed out to you several times already. I do hope you're not going senile !
