Then it's best that he lived and died when he did.
I think people need to get over the whole "sellout" and "Uncle Tom" stuff - there was a real reason why people had those reactions, and one should not discount them. That was a fiber of the time.
But that time has passed, the greater truth has held, and no matter what it all looked like then, and no matter how legit the discomfort was then, then has passed. so let's just get on and learn the bigger lessons. Hell, let's learn the biggest one - that Louis Armstrong was bigger and better than all the shit he went through and put up with and played into.
He was above all that and here's the deal-sealer - he knew it. He knew who he was, more than the business, more than the society, more than the critics, more than anybody.
So let's learn that about his, and then hopefully work on getting each and all of ourselves on that path. Anything else is just blahpidation.
