Whatever Bojt r may be highly distinguished in his field but it does not seem that his field is Indo European linguistics and nothing that you ve said above changes that This might not be very important in other contexts but in the case of the Anatolian Cavalli Sforza Renfrew hypothesis vs the Kurgan Pontic Caspian steppe hypothesis it reinforces a longstanding pattern that very few actual working Indo Eutopeanists have supported the Anatolian hypothesis The Kurgan Pontic Caspian hypothesis won t be too effectively discredited unless more than one prominent respected and well known Indo Europeanist comes out publicly against it And my comments about Janos Makkay were highly relevant to showing how some of his assertions are flawed since he complains about the Kurgan hypothesis requiring linguistic stasis but the Kurgan hypothesis does not require linguistic stasis only a period of sprachbund or dialect continuum while the Anatolian hypothesis does require effective stasis
