Listen PD, Obviously, you have NO idea what plagiarism is. Nor do you have any idea how IRRESPONSIBLE it is to call someone else a plagiarist with ZERO evidence. . . that too, based on your own lack of education. Moreover, you appear to unable to distinguish between what is generally seen as a part of "common knowledge" among educated people and what is not. I guess, that's your problem. That's fine. Since you've been following me around on Sajha -- hurling needless abuse bordering on harrassment, I suggest that you make use of the resource available at the following site: - http://www.mentalhealth.com/dis1/p21-an05.html A sample: "Repetitive behaviors or mental acts that the person feels driven to perform in response to an obsession, or according to rules that must be applied rigidly." Good luck. oohi ashu
