Stop equating ethnicity with abilities or propensities. It is discriminatory, presumptuous and pandering to badly constructed clichés. Worse still is the practice of reinforcing those ill conceived beliefs.
Perhaps those who think so come from tightly regulated, homogeneous and highly insular communities, where contact and exposure to diversity had been minimal.
Why should our abilities be dictated by ethnicity?
Why should our interests be dictated by ethnicity?
Why should patterns of thought be dictated by ethnicity?
If humanity were to be so easily measured, then we’d all turn out according to a scripted and predetermined outcome. However, existing and existence is a lot more unpredictable and far more complex than that.
