Where do you begin? Omigosh, I'm reading this forum thinkin' y'all have the answer to that one!
Seriously, what I've found so far is you can only begin with what you have where you are. If there is some small task that can be done that *might* make a difference, either in the world "outside" or to your own conscience and peace of mind, whatever it is, do it. Take action when your immediate circumstance calls for it.
As for the bigger picture, I would LOVE to ride out there on a white horse and go fix all the problems heroically. But that's a Disney movie. The actuality may be more like each of US from this board taking smalll steps daily - dialogue with a friend about the big issues we're facing, writing a letter to the editor, dialoguing with members of an 'affirming" church, or some days, just solitary prayer and mindfulness. External change takes time in coming - the internal change happens first. Part of what Gandhi meant when he said "BE" the change you want to see in the world. The internal reality precedes it's outward manifestation.
Of course when half the country puts our civil rights up for a popular vote and we start LOSING all these referenda, we want to hurry that process up. If I could wave a magic wand and fix it, it would have been solved years ago. But there is no magic wand and the process will take however long it is going to take. The important thing is that we are engaged in it, and the process is under way.
I'm here ready if a moment comes when I am needed for something more. So is everyone on this forum, and such a moment may indeed be coming.
