I would react to the latest round of genetic genealogy "bashing" (probably too strong a word in this instance, but you get the idea), but Blaine Bettinger, aka the Genetic Genealogist, has already done it for me. I've heard all of this so many times, I'm about ready to put it to music!
Apparently, this round was meant to be softened somewhat by the authors' acknowledgment that some genetic genealogists have a clue, but those remarks were edited out -- as does happen. I've been there myself. And I have to say that what was said was considerably more balanced than many of the negatively slanted headlines would lead you to believe.
Still, it's tempting to pick the Dixie Chicks' I'm Not Ready to Make Nice as that musical response!
