Aside from what everyone else has said, one of the big leaders to this scenario is that the world has gotten so much safer and so much less violent and so much more accepting that people have to literally scrape the barrels to find something to be outraged about.
We all of us know that the Republican playbook of taking rights away from people is a thing that is intended to target people and punish them for not adhering to the moral code of the people doing the targeting.
But the fact that we can spend so much of our national resources on arguing over morality is a side effect of the world being so good that we don't have to argue over worse things.
I'm not attempting to apologize or forgive anybody for their stance, but it is true that we are arguing over whether or not it's okay to have an abortion or whether or not it's okay to be gay rather than whether it's not okay to let have the country starve to death or whether or not it's okay to kill everyone all the time always.
I've said this before and I will inevitably say it again, human history is a pus filled boil on our consciences.
The only way to fix it is to lance it and to deal with all of the pus. We are in the pus clean up stage of human history, and in time with enough constant patient care, it will get better.
