Pedophilia jokes are a little different. Plus rdj went through a quite elaborate process to get back to the big leagues. Comparing rdj who has gone through a redemptive path (part of the reason he was a good fit for stark is the clear real life comparisons) with someone who has literally just been found out to have done something that may be the least compatible thing with a family entertainment company…it just doesn’t work.
Depp is a more interesting comparison, especially since there are definite calls for other people to get his roles given the allegations against him, yet his star power clearly protecting him more than Gunn.
But again, paedophilia stuff is a different subject, different thing to people in general than domestic abuse or drugs, etc. I’m not claiming any moral authority, or objective reasoning that this situation should be so, only that I can understand why it has happened.
I agree Disney are probably being short sighted in this though as well, but I can still understand what their processes is here.
