normally I ignore racial differences... i think $green is the only number that matters.
however, I will say this...
white people are the WORST at clapping. Some are on the 1 and 3, some on the 2 and 4, some on the 1 and 4.
Even something old and trailer and trashy like "Mercedes Benz" by Janis Joplin... they're clapping all over the place. you just wanna hit them with a drumstick or something.
