I forgot about Jack Johnson to be honest. Watched a fair few documentaries on him too. That was more race hate, people hated him because he was black, they then hated him more when he was knocking everyone out and basically unbeatable.

I didn't really think people hated Ali or Tyson as much, Tyson had a cult following and only really got hated towards the end (although his "end" did go a bit!)

I wasn't around during the Ali era, I'd always assumed he was a bit of a marmite fighter.
