Some people are into it

Processing it through another filter, they see the idea more as an enjoyable consenting event rather than something done behind the back of an unaware partner.

They're saying they interpret the post as a consensual act between three people instead of a joke about cheating. They're saying they see comments about things like this and often interpret it like that and others are shocked because they think it's a positive reaction to cheating.

I can but I'll need some help. Where did we go off the rails, or how if that's easier to answer
