Prostasia has become notable for getting promoted by OneAngryGamer in the wake of the UN ban on pornographic artwork featuring underage characters, however their site contains multiple articles defending NOMAPs and promoting regressive leftist conspiracy theories such as the "alt-right" conspiracy theory.
One of the sites they list in prostasia.org/get-help/ is blatantly connected to pro-pedo group FreeSpirits.
Because of this, no-one should support Prostasia as they are engaged in unethical activism.

"non offensive minor-attracted person" is a paradox, to be a pedo is offensive in and of itself.
I think it's actually intended as "non offending" as in they haven't diddled a kid yet
I also belive that it likely means they haven't gone to look at CP, then again individual definitions of nomap may vary...
In this case the "offense" is in the legal sense. In that they claim to be innocent of any crime. Which might be true, in that we aren't at the point where thoughts are crimes yet.
But, as said before, nobody NOMAP described seems to actually be clean in any sense and are just lying outright.
