While this is true, I am tired of cis people defending us as a means to an end. I'm tired of this constantly being brought up that if they take away our rights, they will also take away other rights. Our rights have value too. How about defending us because we're humans and we don't deserve this, instead of defending us just to protect your own ass?
Because that's how we end up with people who are willing to defend our rights but are not actually willing to do anything more than that. They're not defending our right, they're defending the status quo, they don't want to improve things. That gives you the all too typical issue of cisgender people who come to our events and constantly get deeply uncomfortable the second we remind them that they're part of the problem and so on.
A lot of our so-called allies are only allied to themselves.
