Despite the fact that it maybe abused, i think typological studies may help a lot, for example TRB and LBK have different origins, Rösen is either danubean or african but hardly megalithic. At some point one has to decide: Are we going to use it to help as a guide in our exciting journey to the past or are we going to use it to manipulate current politics. A dogma is a dogma ,only the what you substitude in the porter "dogma" changes, but structurally a dogma would retain the initial characteristcs. As anyone can see any monopsone is a stalinist definition. There are only two kinds of politicians: liberals and others. Either we decide to use our knowledge of racial typology on discovering exciting mysteries of the past or we use it for manipulation. I propose to use it in the positive way because we can do it.
