And yet I don't think you do have a point without evidence,
My point is childhood trauma takes a lot of forms and "good natured" showing naked pictures of your children to potential romantic partners the first time they visit (the thing we were talking about) is undoubtedly traumatic for a portion that experience it. I'm not aware of any specific studies studying the impact of showing nude photos of your children to their potential romantic suitors but I do know that childhood trauma has been studied and has far-reaching, unknown impacts. Even if the victim often doesn't recognize the instance as abuse until much later in life, if ever.
