There won't be such a progression for Trump.
Trump has done the math. He knows there are more conservative Christian voters than GLBT voters. That is ALL that matters to Trump. As long as Trump makes all the right noises about "homosexuals", and genuflects to the right right-wing causes, he knows he'll never lose his base.
So, Trump cancelled the Obama executive order that said federal contractors had to have sexual orientation in their nondiscrimination policies. He'll try to kick transgender people out of the military. He will continue to pursue legal avenues declaring that "religious freedom" overrides any and all state and local laws barring discrimination based on sexual orientation. He will have the solicitor general write an amicus brief that the Masterpiece baker has every right to tell gay people, but no other group in Colorado's civil rights laws, to get lost. Thank you, Judge Gorsuch.
As long as the Christian right supports Trump, Trump won't care what happens to gay people.
