Not from the people I dive with and hang out with. We are a non-judgemental bunch who love to dive and have fun. Folks that judge, criticize, humiliate other divers do not last long around us. They are not invited back. Nobody cares what you're wearing or not wearing, unless it is of course unsafe or a potential problem. All are welcome to dive and hang with me...patches or not. Start telling us that your way is the only way and making fun of those who don't meet your standards...and you're history.
