Trans rights keep being eroded, regardless of who is in power, because the Democratic Party isn’t doing anything to preserve them.
... would you like to outline where trans rights were in 2024 in comparison to where they were in 1990, and also inform me which parties were in power in the intervening years?
Dems being insufficient and Dems being backsliders are two entirely different concepts. Dems are absolutely insufficiently supportive of trans rights. Dem politicians are also the primary vehicle through which trans rights have been encoded into law.
