ISIS on the offensive in Iraq

[Seamus Fermanagh]

That's quite OK.. I will of course in return whiff you off as someone who hasn't understood that ethnical differences exist.

Again...all of the differences that matter most to you are more likely cultural in character than ethnic. Ethnicity has only been conclusively linked to a few physical differences -- percentage of twitch muscle fibers, melanin content, etc -- which are not particularly earth-shaking.

When you have a greater degree of variation (genetically, phenotypically, etc.) WITHIN a given "race" than you do between "races," it becomes harder to consider the category significant in a statistical or scientific fashion.
