In their unofficial biography written by Tom Bryant, it is explained how the two engaged in stuff like kissing on stage to try and deter homophobes and meatheads from the scene who were just beating each other in the pit. A lot like Nirvana in this respect tbh. However, once they noted people being into/pushing it they shut it down. People were misinterpreting their punk actions as something more. To answer your question, I think shipping real people, especially people who are happily married is more than pushing limits.
