What does your phrase
" To demean the effort just because the success wasn’t all at the hands of Americans, or the story isn’t historically accurate....well, that’s not really helping much..... " mean exactly ??
Help who ? Hollywood ? the resale value of replicas ? The price of cauliflowers ?
Or are you saying that your average Joe in the US, is as thick as pig shit?
I don't think they would agree with that summation.
It means help to tell a great American success story. Just like I said in my post.
