I do & so do others...this comment from another post perfectly sums up the way I feel about it:
"EXPLOITING Harriet Tubman's image ---- I have to wonder what she would think about having her image placed on a piece of paper that essentially symbolizes the debt enslavement of humanity. My guess is that she would not be pleased and she definitely not consider it an honor. To me, this is another case of appropriating the image of someone remarkable and re-coding it in a way that is just the opposite of who she really was. This is a manipulation! As far as I'm concerned, keep the original images on those bills; they more accurately represent who it was and who it is designed to benefit . They were certainly not created to benefit anything that had to do with Harriet Tubman... Changing the face on the bill has nothing to do with changing a system of debt enslavement and disenfranchisement."
