With the internet, now anyone can be a doctor. Just enter the diagnosis and pull up a bunch of articles on it, cut and paste a few sections in a reply to someone asking about it. The more you can read and cut and paste, the more you can post, and the better doctor you'll be !!
And, if you come across anyone else who can cut and paste half as good as you or better, with whom you disagree, you two might just butt heads and lob torpedos at each other ad nauseum, the torpedoes being lengthy diatribes that you can pretty much guarantee the only ones reading them will be you two !!
