Welcome to 90s/00s Hollywood, we can name A LOT of people who did similar things. Is it problematic? 100% Even years after that we had Emma Stone play half-Asian in a movie but she isnt considered racist. But that doesnt do anything to support the racist claims on JL when no POCs skin was lightened vs someone else and he cut multiple white characters along with POC characters that didnt add to the plot in a 2hr movie. Snyder killed off 2 black characters, Whedon saved one of them. It's very easy to twist some of these things into a certain narrative.
