In the either Hindu or Indian (middle eastern) cultures it's a sign of life and peace I believe, unfortunately, it is now associated with evil. I can understand being offended even though I am not, but you have to fight to see it and if you have knowledge of that symbol, you may not be offended. Again, for 100's if not 1000's of years, it was a positive symbol and should start to be looked at that way if possible. Again, it does not offened me, so it's easier for me to say it and do it than others, but do feel bad if it offend anyone
