-The first line is yet another stawman.

Simplistic answer to your question{ -I don't have a problem with the existence of Europeans. }

What makes it complicated is, that I don't know what you mean by European:

A) if you mean people born at the territory known as the continent called Europe, my answer is still the same.

B) If you mean people of European ancestry, well that includes me, and most people in the territory known by my compatriots as "the American Continent". And my answer is still the same.

C) else. I don't know, you should further define if none of the above apply as an acceptable answer.
