Controversial topics in fiction

I've always loved Cesar Cruz's quote "Art should comfort the disturbed and disturb the comfortable." Good writing shouldn't be afraid to tackle the difficult and controversial topics. The world has moved forward in so many regards over the last few decades (and gone backwards in others). What still counts as controversial?

Depending on your audience ... a LOT.

LGBTQIA+ rights, women's rights and autonomy, economic disparities, racial prejudice, environmental destruction, politics in general, military aggression, police brutality, hate crimes, sexual assault. OMG the list goes on forever.

I think the only point I want to make is this: don't shy away from subjects just because some readers may take issue with it! Go ahead and disturb the comfortable, and let other readers know you see them and support them.
