It's just impossible for white people to be native to any homeland of their own.

White people ain't native of Europe, it doesn't work like that. Humans immigrated from the south and had dark skin. Their skin just whitened to accommodate the lack of vitamin C from colder regions, to simplify things.

However, by the 15th century, there were next to no black people in what is eastern Europe today. The Arabs were already kicked out of most of Europe and there was no substantial immigration from Africa. But there were gypsies though from India, but not in significant numbers.

Don't take the bait. These idiots probably coordinated themselves in a gamejournopro like mailing list to attack the developer because they don't like his political positions, as always, there is nothing more to this. their arguments are always the same, accuse people of racism and homophobia and claim game developers ought to play the social justice tune or they be will publicly named and shamed. There is nothing more to that, don't try to answer these people in a rational fashion, there is nothing rational with these glorified bloggers, they are on a social justice crusade.
