yes he says that west georgians such as svans , mingrelians are not mixed unlike south and east georgians who are mixed with armenians and azeris . he is not really wrong though ....because most west georgians seem to have been more isolated and south and east georgians often get modelled as "60% abkhasian + 40% armenian" or some shitz on gedmatch
but if we are reaaally nitpicky then we could say that svans and mingrelians are rather an offshoot of georgians and not the main kartvelian group constituting georgia
and yes . most georgian members in forums told me i can pass as georgian . some even said i pass easily and one guy said he has even a friend looking like me . but frowning man said i can only pass in south and east but that i look azeri and armenian most
