If you sincerely desire a truly well-rounded education, you must study the extremists, the obscure and "nutty." You need the balance! Your poor brain is already being impregnated with middle-of-the-road crap, twenty-four hours a day, no matter what. Network TV, newspapers, radio, magazines at the supermarket... even if you never watch, read, listen, or leave your house, even if you are deaf and blind, the telepathic pressure alone of the uncountable normals surrounding you will insure that you are automatically well-grounded in consensus reality.
We all know how stupid the average person is. Now realize that, by definition, fifty percent of the population is dumber than that.
