This is an effort to make it look like they are more normal or your more perverted.
I haven't seen the post yet, but people often project themselves onto others. They see sexual innuendo in what someone says, so they assume the someone meant it. In the Bible we are told that David loved Jonathan with a love surpassing that of women. To the SAD mind, there is no love without sex so they claim this is proof that SAD is OK with G-d. They just can't see any other way to view the world.
It's best to ignore that kind of thing. You aren't going to convert the person with the oversexed mind, but it will definately show those on the fence what is really going on.
Shalom.
