From super-smart guy Matt Baume (via Huffington Post):
If the ACA is repealed, as Republicans are trying to do, not only would 32 million people lose health care, according to the Congressional Budget Office, but LGBTs would be disproportionately affected. And “disproportionately affected” is a phrase which here means “get sick and die.”
For example, HIV treatment can cost thousands of dollars per month. Insurance companies that don’t want to pay for that treatment could just refuse to cover all gay people on the basis that gay men are more likely to be HIV positive. Or they could raise monthly premiums just for gays. Or they could create a lifetime cap, so you pay into their system and then as soon as you need expensive treatment, they drop you. All this was legal until the ACA banned it.
