"Many races of, or variations of, humans consistently choose not to cross racial/social or other lines to mate, yet we're still one species."
By this line of reasoning, I could argue that Karen Zerby is a subspecies of homo sapiens. Does the fact that she can mate across racial/social lines mean she is a fully evolved human being? I don't think so.
