I guess you're right that that's unpopular.
But let me put this metaphor out there--if someone shows up in the ER and their leg is badly broken and there's blood everywhere and the bone is sticking out, it is logical to triage that and take care of it first. But if lesser injuries are being taken care of instead, it's logical and appropriate to raise a fuss. The person fussing about their broken leg isn't really making it their entire personality no matter how strident and loud they are--they are simply in urgent pain and need the problem attended to.
Given plenty of trans folks end up suicidal, which is the mental health equivalent of a major physical injury, it's logical and appropriate to try to shed light on what's happening so it can be corrected. That can seem like the community is being "loud" or that an individual is "making gender their core characteristic". But it's more that that is the thing that is currently hurting, so it moves people to try to stop the hurt. Once things have evened out, there's less need to be loud about it, and it will naturally fall into place as a background aspect, like any other facet of a person.
This is generally the case when ANY minority is "making a fuss"--it's happening because there's pain that needs to be attended to. A wound that needs healing.
I've seen more than one "well meaning" person online get upset about how this or that minority is being loud with a tone they don't like.
The thing is--if a person is in pain, they're not necessarily in a mental spot to perfectly frame their arguments just for you, in exactly the tone you need to be able to hear them. Someone in pain can be pretty harsh and mean-sounding, and it's important to recognize the times when YOU are unburdened by that pain and thus have an easier time of being "logical" than the other person who is currently crying out in pain and sounds "harsh".
Basically: have mercy on other people, and understand some harsh things they say because they are in pain, and that you, too, would probably have your discipline fail at some point if you went through something just as harsh.
