Oh dear. I've seen this playbook in the skeptical community and now with LaViolette and Willmott where, in the absence of credible threats, simple disagreement with their goals and methods are seen as "harassment". Heck, I would like to do anything I want and be free from being criticized for it too.
As far as the death threats, two of them, neither of which was deemed credible, all I can say is I bet Mr. Rogers got "death threats". That's what happens when you rise in the public eye where you've got 700 million eyes (generally two per person) and an irreducible percentage of the population are nuts, trolls, attention-seekers and maybe just very drunk with access to someones publically accessible voicemail.
As a blogger, I used to get "death threats" which ran the gamut from wishing a bus ran me over to "I have a bullet with your name on it". I used to send these people a Google Map (actually, probably MapQuest back then) of my address just so they couldn't claim to get lost. The one thing I didn't do was make a transparent appeal to pity.
Alyce LaViolatte feels "harassed" because people wrote nasty reviews and questioned whether she's the sort of speaker you want to have and, in this high-profile case, the lead actor dragging Travis Alexander's corpse through chit and broken glass can only rack up two lame death threats.
Have some perspective.
