A Coming-Out Story

I just read this story of a coming-out.  A ten-year-old boy had a very serious discussion with his mom in which he came out to her as straight.  She had a fair amount of trouble processing this as an actual coming-out, it seemed to me,

Afterward, she talked to her brother about it, who said:

“Babe, he just came out to you. He told you that he is straight. You have to listen to him and work from that for now and acknowledge it and believe it. That’s it. He’s straight. You have to honor that – just like you would if C.J. told you that he was gay. Both of your kids know that you love them and support them and accept them whether they are gay or straight. But, when they tell you like that you have to believe them.”

The fact that this reads oddly to us, and that someone "coming out" as straight seems absurd, well.

Well.

If you can find a better definition of heteronormativity, I don't know what that would look like.
