Once again your presenting the assumption that ethnicity not race as sociology dicates there is one human race divided into ethnic groups can not be a shared cultural experience That is incorrect and a flawed analysis of the subject as culture has nothing to do with biology something you seem to be linking to your argument but a social development that occurs among all people in varying ways A culture can be a shared experience by a number but obviously not all individuals based on ethnicity age religion geographic location and other factors Again the celebration of ethnic diversity is not the same as promoting stereotypes and disassociating any form ethnic cultural tradition is a very basic form of ethnic cleansing
