I suspect a lot of US trans folks who started transitioning in the last decade don't realize how big the Affordable Care Act has been in our access to care.
Almost no insurance companies were covering HRT or other care before the ACA - it was out of pocket or treated as a pre-existing condition, potentially blocking us from all medical care. I don't know that we would have the lively and open trans community today if it wasn't for that. It's also the reason people can access it for cheaper in other settings and why Medicare/Medicaid covers it.
I know it seems stupid, but we might need to do what we can to muster a defense of the ACA (which I hated when it passed because I was advocating for single payer, universal healthcare). It might be one of the most important levers and wedges against efforts to destroy our ability to embody ourselves in the next 4 years.
