This is a very, very personal choice, I can’t make it for you. I have lots of artists whose work I don’t want to look at or support because of their toxic viewpoints. I can certainly understand people feeling that way.
Cerebus, the earlier arcs especially, are undeniably brilliant and a pleasure to read and reread. It took me a LONG time to try them again after some of the awful stuff he’s said.
But the early stuff just seems like it’s written by a different person entirely, and contains some of the best-written female characters in comics.
It’s a very tough call. I don’t judge people either way, but I don’t really advise them on it, either. It has to be your choice. Good luck!
