You have to accept that when you pick a scab off, you're going to get some bleeding. Everyone who reads these posts has an interest in the subject, and a lot of folks just like to voice an observation or opinion. From time to time, there is a pearl in the oyster, and you have to take the good with the less than good. It's entirely possible that some of the conversation is not going to fit with your concept of the subject, and may even offend you. But you have to accept that that is the nature of a discussion, and just deal with it. It is pointless to get huffy and defensive because of human nature.
