Could Benn have been implying a "homophobic" idea? Sure, but he didn't actually say it, so all we're left with is guessing. Really it comes down to this: If you want to be offended, you will add meaning that wasn't there to be offended.
Because I'm a Stars fan, I'll say I assume Benn meant they both poop at the same time.
I get that there could have been undertones, but even saying this gives a small amount of credibility to the nuts trying to make this a story.
The reasonable conclusion is to take the conversation at face value. It's a stereotype, and yes stereotypes are often frowned upon, but twins are often portrayed as having unique or strange relationships: secret languages, attachment issues. Right or wrong it's a perception.
Bob (the host) was clearly poking fun at Benn essentially asking if he an Jordie had that same type of codependent relationship. That's the ONLY thing they were talking about ... not anyone's sexuality. In this PC world, YES it's frowned upon to acknowledge a stereotype. Shame on them. Move on.
They were talking about their facial hair for goodness sake .... not who they are attracted too. It was a dumb conversation about how "odd" to them is that the brothers coordinate down to their hairstyle and seem do mirror one another. It's low hanging fruit radio that in no way question either Sedin's toughness, manhood, or sexuality.
