Actually, if I were you I would be greatful rather than defensive. These people have replied to warn you of potential risk of cross-contamination with really nasty bacteria. Would you want to be responsible for someone's serious health decline after having contracted B. cepacia at your event? Furthermore, Saveferris did not call you dumb. I think this can be an extremely important lesson for all of us. You CANNOT go by what somebody told you, nor can you believe everything you read on the internet. You must know your disease inside and out. That includes treatment options, medications, complications, risk factors etc. The more you know the safer you are. This is a public forum where skepticism and questioning should be welcomed and respected. If, in fact, you are speaking the truth, all the questioning in the world should only make your case stronger. If it turns out you are wrong, you should welcome the opportunity to learn.
