HBDchick is an advocate of Human BioDiversity theory, which, very simply, states that the distances between various populations of humans over time have lead to statistically relevant and measurable differences in both mind _and_ body (this is the crux of the issue). While this is intuitive within the whole of mammalian evolutionary biology, there are some very sensitive conclusions that any party could arrive at if one accepts that different groups of humans have evolved different traits that reflect both strengths and weaknesses in modern society. She is not alone in this assertion, but the status quo of politically motivated science has tacitly decided that exclusion and censorship are the best response to an admittedly uncomfortable possible interpretation of reality. There is a huge amount of reading on the topic, but i refuse to use throwaways and i do not want to be banned so feel free to DM me if you'd like to know more. IANAB.
