A.k.a. “Anti Vax Warrior”
Small fish, but worth a mention. Lowell Hubbs is an online troll whose mission is to spread FUD about vaccines and vaccine safety. Hubbs has no education or experience in any relevant field, but tends to repeat standard antivaxx tropes and conspiracy theories, claiming for instance that all vaccines are unsafe and ineffective (that better sanitation and nutrition, not vaccines, account for the decline in vaccine-preventable diseases, which is almost as delusionally ridiculous as flat-out denying gravity); instead, vaccines apparently lead to autism, asthma and SIDS. To hold those views, you also need some serious conspiracy theories, and Hubbs is not afraid to go there (“I like whale.to, its a great site containing more real history than I know you can actually deal with,” says Hubbs; whale.to is a frequent source of his information, apparently): In 2011 Hubbs even concluded that his site, lowellsfacts.com, had been taken down by Immigrations and Customs Enforcement. It wasn’t.
Of course, Hubbs thinks that his claims are backed up by science, but seems genuinely not to understand the difference between a scientific study and a blogpost on a conspiracy website. He does complain, though, that his critics seem not to bother to review his work. His ridiculous nine vaccine questions addressed to non-loons are addressed here. Many of his antics are covered here.
Diagnosis: Hubbs is really not anything but a trivial troll, but he is a rather active one and his impact on civilization, if not major, is certainly not beneficial.
