I'm trying to stay calm and hopeful about this, but I feel insecure about things getting better, and I keep stressing about it.

I do this, too! For the very same reason.

My solution: basically hedonism.

These right wing fools want to go to war and kill people over trivial bullshit like who people love and what books kids read. And no one with real political or social power is doing a damn thing about it. All thy environmental problems, including climate change, I suspect will only make it worse.

So fuck it. Live, laugh, and love now.

Do you not have any Muslim friends?

I have failed to find ANY positive information, and news about these topics, and because of that I am very worried that the world will become a Right-wing dystopia

If it makes you feel any better, significant percentages of young Muslims are leaving the faith, and I'd expect this trend to accelerate and continue. Worldwide people are moving away from religion and Islam is no exception. In fact I expect there are many more nonbelievers in the closet due to the harsh penalties for being an apostate, (traditionally leaving Islam carries the death penalty.) While Islam will continue to grow for a while because of high fertility rates and indoctrination I believe the writing is on the wall for all religions.
