are raging among the creator of the original Coexist logo, Polish artist Piotr Mlodozeniec (above); the folks who trademarked that logo and began selling it on t-shirts etc. without Mlodozeniec's permission; and the folks who created the famous bumper sticker (below). Mlodozeniec says he isn't bothered by competition from the bumper sticker version but he is aesthetically annoyed because he considers it terribly ugly. I like it. But knowing that the people behind it can't coexist is troubling.
