If it were me, I’d probably put it down — for now. We are actively living through some fucked up history. Time and distance will not change the fact that an entire race of people is being murdered, but they may make it easier to get through. Especially if Bibi gets what’s coming to him someday. (Not that I’m holding my breath.)
Ultimately it is okay to put a book down for any reason. If something is getting in the way of your enjoyment or you’re being distracted by things outside of it, you’re probably not getting as much out of it as you otherwise might.
