Note that I'm not saying there aren't good faith inquiries to be had, but it is really hard to have these with racist agendas being pushed whole claiming "neutral" questions.
A few observations that I would like people to keep in mind when looking at these fields:
- the people who complain about being "silenced" continue to find funding, public platforms to push their research and in some cases, tenure
- the "hard questions not being raised" seem to cluster around the question of differences between "races" and less around whether the concept of race actually makes sense in humans (AFAIK geneticists generally think no), whether these differences might be socially constructed (yes, that's possible. If there are systemic social biases against groups with genetic genes the impacts of these will be 100% explained by the presence of these genes in data, but 0% genetically determined as in biologically determined). And often they are then raised to dismiss concerns about the systematic problems which might have caused the measured problems
- scientific racism and shoddy science in this field has a long history, and people carry their misconceptions around. Famous examples are "objective" written IQ tests given to barely literal test subjects, or asking trigonometry questions, Both of which test the schooling of the subjects more than the IQ
In an inherently political field of science, denying the political nature and implications of questions being raised and the manner in which they are raised and trying ot claim "objectiveness" is in and of itself a political tactic.
