It's also very worthwhile to note that groups of well educated, titled experts do horrible things now and then. Take the lobotomy for example, which won it's inventor (Dr. Egas Moniz) the Nobel Peace Prize.

The same argument goes for electroshock therapy, forced sterilization of 'mongoloids',

and a whole bunch of stuff done in World War II. How about lead based paint?
Learning is filled with mistakes but 'Trust us, leave these things to professionals. You could really hurt yourself.' isn't an answer.
What people do with their own brains, ultimately is their own responsibility.
