I'm basing a character on this kind of fellow! Excellent reference material.
He must be fun to debate with.

The additional context that this isn't a single incident is important. He spends a great deal of time emailing anyone that has anything to do with writing and goading them into reading his theory.

"Feel free to continue to ignore my work, just be prepared to pay a price for it that you might never have imagined.”
And, he pushes his agenda in newsletters, his website, the twitter feed I referenced, etc.
The context, to me, is meaningful. This isn't a case of outing someone. He outed himself from the start, on purpose.
Reading the article by itself, you might draw conclusions that you wouldn't if you had the full story.
