>Acknowledging and accommodating gender dysphoria discomfort costs cisgender people nothing and unlocks the productiveness of an additional population in society.

This seems like a pretty broad generalization. Forget the semantic fact that by definition, accommodating something takes effort. Some people's worldviews may not account for gender identity being expressed this way. Whether you agree or disagree with the worldview, saying it costs them nothing to acknowledge it seems pretty unfair. Especially when it assigns a label to people its imploring to be accepting and accommodating of. It's a strange way to try to win allies.
