Hurdurr whataboutism! You found a research paper that literally states that there is no evidence of eugenics finding institutional roots that would indicate a flourishing of eugenics but instead focused on improving environment, social, and educational conditions of people so that people would become better people over time. Compare that to the actual forced sterilization of fully a third of the colonial US holding of Puerto Rico, the mass murder of 7/8s of the indigenous population in the Americas followed closely by the destruction of their environment and destruction of their social and educational behaviors followed by the forced kidnapping of millions of indigenous children and their subsequent re-education by physical, psychological, and sexual torture to remove their language and culture and turn them into obedient slaves of the white ruling class.
I mean, you’re a sick fuck if you think this paper is anywhere near capable of being compared to US eugenics, let alone what was going on in Europe at the time.
