In my humble opinion, you are free to believe whatever you want, but start preaching and you got to live it! These sorry excuses for jesters ought to suffer the consequences of their teachings and just discard living with anything that is associated with the undoubtably true and false in "racist" math.. Good luck with that PC, internet, gps, building, medication, trip to Mars, smartphone, powerplant, car, lathe, chemistry, bridge, reducing CO2 emissions...
