graduation phenomenon 

The tendency of transgender individuals to drift into the background and away from the trans community the farther along they are in their transition. That isn't to say that they no longer identify as LGBT, but rather, their involvement in trans support groups, trans subreddits, local trans events, etc. wanes with time as they become less in need of active support and less able to relate to younger trans (baby trans) experiences and concerns like the onset of the effects of HRT, the process of coming out, getting all new clothes, and (especially for those who have had bottom surgery) bottom dysphoria.

If they are a trans lesbian (transbian), for instance, they may continue to attend pride events, but focus more on being a lesbian than being trans because being trans has essentially moved to the back of their mind; it's no longer something they actively think about beyond administering their estrogen.

"Why is it that most of the trans women here don't mind their genitals, when statistically, most trans women want SRS? Are we outliers?"
"Graduation phenomenon - they all got it and moved on."

The graduation phenomenon accounts for much of the ideological divide between so-called baby trans and elder trans individuals.
