I don't need to color you as you did a good job yourself. To be frank, bringing up PC was the red flag that made me realize that you are being a bit disingenuous. The paragraph I focused on was a big WHAT THE FUCK for me. I see that you are sensitive and you should be when you have gone so far out on a limb postulating to the point that you are coming across as wrestling with transphobia. To be clear, I am not saying you are transphobic, but I am suspicious based upon your arguments.
Having said that the vast majority of what you say is helpful and respectful. I do appreciate that.
Statistical analysis already takes into consideration your points so I am not sure where you are going except maybe just treading water before you go completely under. It really doesn't matter what you say or think as we already have the empirical evidence. You are welcome to refute it with your own statistical analysis, if not we can just accept it.
You may be reluctant to say suicide rates should be equivalent, but based on the research I provided you shouldn't be. Statistical analysis already accounts for your misgivings, that is the whole point. While transgender people are a sub population they are not particularly unique by any metric and saying a non-trans person is an Apple and a trans person is a orange (or maybe the other way around) is a comically bad example.
Assuming trans people are not similar to the majority group conflates demographic distinctiveness with baseline human biology and statistical methodology. In research and statistical modeling, assuming a shared baseline between a subgroup and the general population is standard practice.
Across the vast majority of biomedical metrics such as cellular respiration, basic pharmacokinetics, cardiovascular hemodynamics, and organ function shows that human beings share identical foundational physiology.
The differences between transgender and cisgender cohorts generally pertain to specific variables such as exogenous hormone levels, surgical history, or distinct social determinants of health like minority stress. Outside these specific physiological or psychosocial pathways, assuming divergence has no biological or statistical basis.
Assuming trans individuals are completely distinct across all parameters creates an unfalsifiable exceptionalism that undermines valid comparative research. Meaningful statistical inquiry examines differences where plausible mechanisms exist, while maintaining standard population baselines for everything else.
The only thing that appears to be twisting is yourself as you have hung yourself (no pun intended) out to dry. I won't be down voting you or blocking you because it is important to address the issues you have brought up not only for your benefit, but also for everyone else who is here. Besides, like I said, you appear to be helpful and respectful. While I do not agree with your misgivings, they are not completely irrational (just mostly).
