Excellent and thanks for the backgrounder. One thing that surprised me about his data was his acceptance of a 5-10% rate of homosexuality among the general populace. I thought the best numbers we have put it in the 2-3% range. Do you know his source or if he’s backed off that larger figure?
The 10% figure was an example of the “jamming” technique used by the left.
Jamming: Promote the appearance that something rare and aberrant is ubiquitous.
Part of his method was to deliberately introduced biases in the direction of the politically correct conclusion (hence treating children raised by homosexuals who wouldn’t specify their sexual orientation as heterosexual). Not quarreling with the PC estimate of prevalence (5-10%) is simply part of the method. It makes it makes his conclusions stronger and politicized criticism of the results harder.
Knowing him, I’d say he intentionally cited the higher figures in research because it still showed a statistical difference but also avoided any claims of personal bias on the part of the researcher.
