He was the ‘race and IQ’ guy on the slatestarcodex reddit. He posted A LOT about race and IQ. He also famously made it to the ‘quality contributions’ thread of that place. Describing his ideal world. A small quotation: (there is more, a lot more):

• Mandatory abortions of the congenitally ill.
• Corporal or capital punishment for adultery.
• Adultery as a civil crime.
• Mental illness/having mental health medication prescribed disqualifying voting.
• Lower tax rates across the board for more fertile people.
• Paid sterilisation (i.e., trading your fecundity for a basic income).
• National genotyping and IQ scoring as part of using any sort of public health subsidisation and education.
• Allowing insurers more room to discriminate on any quality they wish, including genotype, education, and IQ (i.e., no more disparate impact or genetic discrimination laws at all).

Nice guy, no issues, normal type of quality contribution.

“T*PornO is one of our most prolific and high quality contributors, and his eccentricities don’t do anywhere remotely enough bad to overcome the good he does by being around here and posting.” Salt the earth.
