Yeah as someone who says I have AGP for me it means I have an AGP fetish. It's not a sexuality it's not an identity it is a fetish.

Now sure there are cases like Malo brought up but I think that has a deeper social, aesthetic or a variety of other reasons why children may be overly invested in how the other gender behaves and how that can morph into a sexual fetish as it doesn't always. In large from my observation it is one though most of the time.

Should people be incredibly ashamed of it? If you aren't harming anyone or infringing upon anyones rights and it's not inherently self destructive i would argue no.

The problem is many people in the trans community just have a fetish but are trying to conduct their entire identity around said fetish and involving unwilling participants. That or they have been gaslighted into thinking being GNC means they aren't a proper example of their birth sex.

In some ways for the less predatory types I just think they have severe depression, feeling like they have failed their birth sex and think transition offers them a new life or are ashamed of their fetish and are looking for legitimacy in the trans movement. Plus maybe not confronting they have an unhealthy porn addiction where they want to make their real life their fantasies.
