Race has little to no biological basis and is primarily a social construct.
This is an objective fact and should have no correlation with political views.
Sickle-cell anemia says hello. 
Obviously genetic traits can show up in ethnic groups. Doesn't mean that "race" is real. A Greek is not necessarily more closely related to an Icelandic than he is to an Ethiopian.
Try harder next time.
Once again, the DNA evidence does not agree with your predetermined conclusion:
Stop. You're just humiliating yourself. Ethnicity exists, obviously. Genetic traits among closely-related people exist, obviously.
The idea that humanity is divided into 3 (or is it 4? 5?) "races" that are all more closely related within each other than without is not supported by DNA evidence. It's all a big continuum.
Arguing that a variable is continuous rather than discrete is very different from arguing that said variable is nonexistent.
Which is great, except in this case there's significantly more genetic variation, for example, within Africans than between the average African and the average European
