a niche for another board...

B4U-ACT and Virtuous Pedophiles both have made the rule in their peer support groups that pro-contact and anti-contact debates are prohibited. It leaks out around the edges now and then, where either view can leak in B4U-ACT, but only the anti view leaks out in VP. They are both closed to public view -- you have to join if you want to read what's going on.

There is no obstacle to creating a similar group for the pro-contact position. Nor is there any obstacle to creating a group that shares girl moments and pointers to cute girl pictures with no political discussions at all. Such a group could allow erotic text posts to varying degrees. Maybe some other groups do approximate those, I don't know.

But obviously GC has decided to allow and encourage debate of these issues. When Dissident makes a top-level post "Concise refutations of common anti arguments", he's clearly inviting a debate.

For better or worse, the whole world is watching. I know of one and think I recall a few other cases where scientists wanting to study what pedophiles believe did an analysis on GirlChat posts.

One could also create a group where debate is allowed, but some positions are out of bounds. A version of that exists here necessarily because of the rules against describing or promoting illegal activity.

I think GC has taken the shape you would expect given the rules it has chosen to operate under.
