If you don't follow it, Palestine/Israel can seem like a complex issue. Marc Lamont Hill's book is very short and to the point. Like 150 pages. Four chapters. You can do it.
(I mean it's pretty accessible even if you don't regularly submerge yourself in political reading. I think it hits the high points of historical significance too so you won't be in the dark.)

He goes into why single Israel out/is it being singled out, what does "right to exist" mean exactly, criminalization of BDS and nonviolent protest, Trump policy as a continuation of US policy, finally how Gaza got separated and turned into an open air prison.

He's honest, unlike many, about conservative (obvi) and especially liberal opposition to applying our stated values of freedom, dignity, safety, and self-determination. This is what i always want to hear from politicians purpoting to espouse these values. Every one of them need to read this book.

Liberals need to start advocating for rights consistently across the board. No more exceptions for Palestine. It seems obvious, but it's something that still needs to be said. Like black lives matter and women's rights are human rights. We have to force policy in line with these fundamental rights and beliefs.
