I’ve done a bit of research that may help to outline this issue.
The lists below come from the GLAAD.org web site. A number of these organizations are national in scope. The second list is of LGB organizations that include programs focused on transgender issues. Among other things, it is useful to note that the National Center for Lesbian Rights has done a lot of legal work related to the transgender exclusion in the military issue.
Politics is always a numbers game. As trans people, we are quite small in numbers. In 2016 the Williams Institute at UCLA released what is, so far, the most comprehensive study regarding the numbers of trans people in the US. What they found was that the national average is about .6% of the population. That equates to roughly 2,000,000 people. The number 1,400,000 also appears sometimes, but I believe that only covers the adult population. There were 4 states, including California, that are at about .8%.
California has about 40,000,000 people, so the trans population is about 320,000. If you consider the gay population to be 10%, that means that there are about 4,000,000 gay people here in state. Basically there are MANY more potential LGB voices than potential trans voices.
Financial resources also come into play. Trans people tend to be better educated than the general population, yet our unemployment numbers are about 4x higher. It stands to reason that we tend to have less disposable income with which to support advocacy organizations.
Regardless of what we may think of trans-specific organizations, it is very hard to compensate for a smaller population and fewer dollars.
