I bet if they had a Reagan character acting gay or something bashing Christians they wouldn’t have walked out.
Not as a group. Because it's not their group.
But maybe not automatically assume that everybody would be okay with some scenario you dream up. Maybe as an individual somebody would say "Enough is enough" and walk off the picture. Who can say? I'd be surprised if somebody hadn't already done that on one of Sandler's projects.
I wonder, though, if these guys had gone through with the Wild, Wild West and Lone Ranger updates, which were pretty awful.
