One of my quilts was raffled and the winner gave it to a local charity. I was not offended, but even if I were, It was no longer mine. Many people are offended by any little thing. I think that in the long run, that is their problem, not mine. You won. It is your property. Only you can decide to what degree their feelings should influence your life. A quilt of mine was purchased at auction last year by someone who apparently buys them then re-auctions them for an urban charity. Peculiar, but perfectly legal.
