Unless he's buying something, ignore the emails. You're getting reaction from him because you continue to respond. Quit responding and they'll go away - and what are they going to say? That you wouldn't respond to them anymore? Someone like that posts that online and all anyone is going to say is "I'm not surprised".
I had a guy email me a few months ago questioning some stats on my page and the resulting conclusion. Seems he'd done some internet reading and come to a common (but mistaken conclusion). His email accuses me of contributing to misleading information and he wants a detailed response as to why "I'm one of those businesses that perpetuate the myth". Except what he was assuming was the actual myth. My stats and conclusions were created with the help of a credentialled statistician (the complainer funnily enough was a gov't scientist). As much as I would have liked to have responded, I dragged his email to my 'go away' folder and never responded. If I'd have emailed him back, we'd still be picking apart stupidity today.
