If you don't like the subject of health........... If you don't like the subject of religion don't read it , pass it up..........but don't trash it because you do not want anyone else to read it................................. I agree if the only intent is to abruptly end the conversation.
One of the problems we often find with subjects such the above-mentioned is that both proponent and opponent feel strongly about their subject matter. So if a poster is on a roll to pitching a point s/he feels is a panacea then s/he can be quickly taken aback when another poster posit an entire different point of view and especially one that is direct competition to the original poster's revelation. I believe this reaction counter reaction is common place between scientist for many reasons among them the heavy investment made in such projects, ego, competition.......................
Likewise with religion where the heavy investment is emotional because of deep seated feeling and the energy needed to complete this process of pure love and commitment.
I suspect that is why some people stay away from the subjects of religion and politics.
In my case I stay away from the subject of cooking because I get very emotional about how some food should be prepared and there is only one way to do it...its my way or the highway
