Although this website is primarily about non-offending MAPs, it still has some interesting resources criticizing the mainstream narrative that all MAPs are evil child rapists.

In the research section they talk about the experience of MAPs regarding the age at which most of us start to understand our sexuality, and our experiences regarding mental health. They also talk about how society should reduce the stigma towards MAPs, and how not everyone who abuses a child is necessarily a MAP.

Overall they have some useful resources that can be used to argue in favor of MAPs from an abuse-prevention/non-offending perspective, which I think is a good starting point for the destigmatization of MAPs as normies tend to be more receptive to these kinds of arguments compared to pro-C arguments.
