Offended by the Puzzle Symbol?

I have been looking up tattoo designs looking for more details of a piece I am sketching out and going to get in honor of Michael. I found a section about the discussion of puzzle tattoos, and I was suprised how many people are offended by the puzzle being the symbol for Autism and Autism Speaks.

The way I see it, Autism is a puzzle, and it is one that is full of tiny pieces that are hard to place.  Once it is all placed together, I am sure the results could be beautiful. Michael is like a puzzle, with a few pieces missing. But he is not greedy, he is not vengeful, Michael appreciates things like Halloween and Birthdays with a different passion than "normal" children. So maybe in a way, he is blessed by missing a few pieces, he will see life in ways some of us could never.

I still plan on getting my tattoo with the puzzle piece, and know even if it offends some, I am standing up and saying I am proud and unashamed of my Autistic son.
