Right, but DHH's argument isn't about cultural homogeneity for the sake of it, but rather the consequences of what the other cultures have brought. Reading further from links from the blog, either to his other posts, to the Tommy Robinson march, etc., would tell you that. I.e, you conflate race with merit - because they do associate in the statistics sense, but one is not the other.
The OP on the other hand demands funds from a private company, main argument being that "this other person, who I don't like, got money, then a website I do like, should too".
