People who take action instead of just sitting on their laurels and criticizing others are the ones who have the most credibility. If you had worried about folks who waited to "snipe" you when the chance came along you need to realize there will always be people like that out there. As long as you believe in what you are doing and it isn't illegal then you aren't any less of a human being than what some of the detractors may have been implying about you, don't worry about it in other words.
