Where was the homosexuality in that movie? Was there a gay couple for a couple of seconds when they first arrived in the real world?
I'd guess they are just having a problem with the ideas about patriarchy that it puts out there and banning it for homosexuality is just something that's easy to do?
First their generation creates a problem thinking it won't affect them and now that it starts threatening themselves they suddenly start having a problem with it - exactly my mind of humour...
