> when CPS is told about potential abuse they can take your kids away, and this is not theoretical, it has happened
No, they cannot and no they have not. It was put on hold by the courts, and families were investigated without children being seized [1]. Together with the mass resignations at Texas’ CPS [2], it’s a potent example of the difference between a nation with the rule of law and an active civil society willing to make sacrifices and one without.
In addition to what JumpCrisscross explained to you, that document does not support your original claim that someone telling CPS your kid is trans leads to CPS taking your kid away. It says that it's illegal for you to facilitate or subject your kid to permanent, irreversible surgery on their genitalia.
I suspect if you let your 14 year old kid get a tattoo, CPS would have questions. It seems reasonable they should also have questions if you're encouraging them to get irreversible genital surgery.
