I wouldn't even consider myself 'religious' but yeah... they had full opportunity to consider what they were doing and stop themselves. This has little to do with being "correct" and everything to do with not being assholes.
There is no "correct" way to threaten someone with Rape (whether that be an individual, or in this case, a group of individuals) from a political stand-point. Because doing so is just disgusting and wrong in any context.
