Please use the comments to demonstrate your own ignorance,
unfamiliarity with empirical data, ability to repeat discredited
memes, and lack of respect for scientific knowledge. Also, be sure to
create straw men and argue against things I have neither said nor even
implied. Any irrelevancies you can mention will also be appreciated.
Lastly, kindly forgo all civility in your discourse . . . you are,
after all, anonymous. -- Barry Ritholtz
