Isn’t this a much smaller audience than David Irving had back in the day? And didn’t, back in the day, historians of note and reputation like John Keegan and D.C. Cameron Watt go the extra mile in defense of Irving—publicly regretting that he lost his case against Deborah Lipstadt and Penguin, and that her book was not pulped in the UK and Lipstadt and Penguin made to pay damages to fund Irving in the lifestyle to which he aspired?

Seems to me that we are actually in considerably better shape than back in the day. It is just that social media gives all ideas much more reach (and much less depth, as one’s attention gets so scattered, as it does).
