When I was a teenager I was a militant atheist and a vocal, in-your-face liberal.
I’m still an atheist but there’s really no reason for me to talk about it. And I’m as if not more liberal on abortion and LGBT (well it was gay marriage in particular back then), the issues du jour of the mid-00s (first voted in 04). But being surrounded by rich technocratic neoliberals spurred on my transformation into someone whose worldview is about improving the lives of the American poor/working class/lower middle class (particularly those left behind by change).
That...should still place you firmly in the democratic party and certainly not inspire you to vote for Trump. Pretty much everything the Biden administration is trying to do will improve the lives of exactly those people.
