The long and short of it is that legalizing gay marriage isn't even a strong step to lgbt liberation, it is literally just tepid assimilationism. We are only "accepted by federal law" in most narrow and on their terms sense. Call me when the US government federally covers trans Healthcare, makes conversion torture a federal crime, deals with the queer(especially child) homelessness problem, and purges the people calling us all pedophiles.
Also, learn some fucking humility.
