I didn't really have any idea who this guy was before joining this site a month ago (beyond hearing his alias mentioned amongst my colleagues once or twice in the past). After starting a thread on what I thought would be a productive discourse a few weeks ago, he attacked me for no reason and tried to derail the thread (which led to it being shut down). Intrigued, I took a look at his posting history and it turns out he tries to do this on just about every single discussion topic he comments on. His input is sarcastic, demeaning, and all around unprofessional. I truly hope he isn't actually an administrator who has any leverage in the medical school admissions process. The idea that someone like this is affecting the futures of hundreds of premed hopefuls makes me cringe.
