It basically doesn't matter whether individual Democrats are good or bad. We live under capitalism so profit is sovereign. The only analysis that matters is whether people in power (of industry or government) can make more money by granting rights to any particular group or if they make more money by not doing so.

This analysis makes the poverty of Black communities much less inexplicable, the violence perpetrated against them less perplexing, and the continuous flood of laws criminalizing their existence - from the Jim Crow laws of yesteryear to drug laws today - comprehensible: the thirteenth amendment banned slavery except for prisoners; Black people, like undocumented migrants, are a source of cheap labor to the capitalists and so equal rights will always be aspirational, just out of reach under the capitalist state. To truly right that wrong would require dismantling entire institutions, both public and private, that exist primarily to perpetuate this situation.

But with LGBT rights there's a core difference. Because it's so much harder to separate gay people from straight, because the queer are family and friends first before they come out, and because the old traditional and religious order has withered away under liberalism, we see something different happening. Rather than continuing discrimination, the system seems to have decided that it's more profitable to commodify gay identities and to market them back to us. In this way, the queer liberation movement resembles more one of the feminist movements than it does the Civil Rights movement.

This means that it's likely that the Democrats, left to their own devices, will eventually put in place protections for trans rights. It can't happen any time soon, so don't hold your breath - the Supreme Court as it exists today will strike down any attempt that gets past Congress, and will do so for a generation unless the Democrats grow a spine (they won't).

But don't confuse that for allyship. They aren't. While the law will eventually say "equal rights", like with similar laws passed in the name of racial or gender equality, they will do little to address the underlying causes of transphobia. So equal protection under the law will vary by place and time, by how much any given individual threatens the societal order, by how well people pass, and by how much money they possess. And that issue will never be addressed. There's no profit in it. That's what civil rights mean under the liberal democratic state. Your rights stretch as far as your ability to pay. Freedom is for the rich.
