no, sex education presents facts and does not attempt to turn anybody into anything.

there is no relationship whatsoever between sex education and "conversion therapy" - in fact, they really cannot be more distinct

The purpose of evidence-based sex education is to empower people to make their own choices.

The purpose of "conversion therapy" is to force people into the choices they might not make by themselves, most often to their detriment. It basically dictates to people what they should do, feel, etc. In that sense, it is not "therapy" at all, because the most basic tenet of therapy is that the client should not be told how to feel.

Where is an overlap?
