Since you have mis-defined racism and called me a simpleton it is hard not to laugh. Yes, one can tell a joke about a race and not be racist.

99% of people here are not racist but every large group has some. Do you believe that you never read racist posts here?
Oh jeez...
: a belief that race is the primary determinant of human traits and capacities
