We've crossed a few bright lines on trans rights. In addition to the "harmful gender ideology" framing, we're explicitly describing trans people as dishonest and trans healthcare as mutilation and abuse. This spans a few different EOs with slightly different contexts and they're pretty dense, so this'll be a long one.
Military: current and future active service members who are trans will be discharged as they are mentally and physically unfit for service. This is the section where language of dishonesty and immoral behavior is introduced.
Prison: there will be no trans care provided (allowed) in prison, and trans inmates will be housed by sex at birth. This also includes how they're allowed to dress, keep their hair, etc.
Healthcare generally: federal funding will not cover any form of trans care, and federal funding will not support any organization that provides services to trans kids. This latter one has been tried before and successfully pressured hospitals to shutter their programs for trans pediatric care, which, for the record, does not and has never meant surgeries on kids. It's puberty blockers, which delay wrong puberty until kids are older and choose to proceed with transition in other forms. I'll leave further explanation to this comprehensive thread by @chandlerc with receipts: https://hachyderm.io/@chandlerc/113909097204877205
Parenting: doubling down on the framing of supporting trans kids as abuse, a new EO classifies (nonexistent) procedures as female genital mutilation (an actual and unrelated act of violence) and invokes laws relating to kidnapping to be used on parents of trans kids who flee from less safe to more safe states within the US.
