I can't imagine what "pandering to" in the context of proposed legislation means.
If you (general you) want to oppose this bill because it's not the right type of person who is proposing it I'm sure you will be able to join up with any number of (trans rights) groups lobbying against it.
If you want the bill to go through you don't have to do anything- the process will run its course.
If you feel strongly that the draft bill is the right thing to do you can write in support. It doesn't mean you (general) you are bound to the Republicans ever more.
