Trans rights are human rights.
It's a short enough sentence that isn't short on meaning.
Anyone who isn't concerned is either not paying attention or an enemy to all human rights.
Anyone who thinks trans rights aren't their problem because they're not trans themselves is both missing basic human empathy and dangerously blind to the fact that fascists won't ever stop there and will keep attacking their next targets until all rights are trampled.
If people can't stand up for the most vulnerable among us, then our rights will always keep eroding.
