Legislatures decide policy, not constitutionality. The courts decide whether something is constitutional or not. Courts (usually) do not pick among different policy choices. Just because someone is pursuing a policy preference you truly despise doesn't automatically mean it's unconstitutional. The courts can't and shouldn't rule on the political merits of a given policy. There is a whole universe of policy initiatives that I don't like but which are not unconstitutional. Suing your way to your preferred policy outcomes won't work in most cases. In short, the courts will not save you from all of the effects of a Trump Presidency and Republican control of both chambers of Congress. Only the people can do that. Like it or not Trump won. Right now the only people who can legally remove him from office are other Republicans. That's because, drunk on moral certainty, starting around 2010 Democrats forgot how to win seats.
On policy questions, no political party or movement can accomplish much without winning over voters. Obtaining voter support doesn't mean that you must agree with every "deplorable" voter stance. It does mean though that you must visit the voters, listen to them, be seen to work on their issues, and build both a logical and emotional argument on why you and your policy are their best options. Hectoring them and lecturing them don't work.
I didn't invent this analogy but I think it's still relevant. Let's say I see you drinking a glass of dirty water and I want you to stop. Will I be effective if I tell you that only a stupid inbred muyerfuyer like you who comes from a long line of stupid inbred muyerfuyers drinks dirty water. Well maybe. You could be a mentally slow person with an unfortunate family tree. Sometimes shame motivates. But I'll probably have a better chance at changing your behavior if I sit down and pull out my own glass of clean drinking water. I explain why I drink clean water, what you will gain from doing the same and hopefully influence you to reason towards your own (correct) decision.
Or don't change a thing. Continue to scream that you're here to smash the eurocentric cis-het patriarchal nationalistic racist transphobic misogynist ableist homophobic power structure. And continue to be surprised when you lose elections.
