Defining dangerously mentally ill is not so easy. A rabid, foaming at the mouth person, threatening others, with with the ability to act out, is an easy enough call. If all the shrinks were conservatives with their lights on, I'd be a bit more comfortable with the idea. As it is (or could be), someone accuses you of "dangerous thoughts," you are detained for evaluation by someone with letters after their name who doesn't want to be held liable for anything you might do (or who doesn't agree with your political views); you have no rights and are forcibly medicated; each day becomes a sedated blur. If and when "they" decide to release you, you've lost all credibility and resources. Sounds like a libs dream come true.
