Make no mistake. Trans people, especially trans women, are the canary in the coal mine. If the United States government manages to pass legislation making it essentially illegal to be trans again, mark my words it WILL continue on up to sending us right back into McCarthyism and the “kill or imprison anything you disagree with or dislike” policies of the 1950s (not that that hasn’t already been happening under the radar, but it’s going to be More).
There really are people out there who are acting like suggesting genetic testing to “confirm the identity” of a group of people isn’t a wildly dangerous thing for a government to start doing. This is not a door that should be opened.
