Improving dream recall isn’t necessarily important for lucid dreaming—I practiced lucid dreaming for some years without any explicit attention to it. I can imagine ways it would be helpful: analyzing your dreams will help you recognize when you are dreaming, plus there’s not much point to a lucid dream if you don’t remember it.
My fears are more on the opposite side of things; some people advocate lucid dreaming methods where you slip directly from wake to lucid dream, but this requires passing through some rather terrifying states of consciousness I can’t bring myself to intentionally experience.
I don’t know which communities you’re talking about, but anecdotally I have to say I’ve found trans bars and support groups to have a much broader range in race, class, and origin than any other places I typically go.
Also, low testosterone you describe in that paragraph is not implicated as a cause of transgender behavior, with people generally being in the typical range for their birth sex before transition, which includes outliers with very high testosterone levels. Giving people additional testosterone has been tried and not been found to “cure” transgender behavior.
Relying on made-up facts for an entire paragraph of your purpose statement is not very encouraging.
