For those who don’t know, a ‘MAP’ is a ‘minor attracted person’, it is the terminology of choice on tumblr, where you can find ‘MAP positivity’ blogs. The nested triangles is a paedophile symbol going back to PIE (Paedophile Information Exchange) and NAMBLA (North American Man Boy Love Association) days (the het paedophile version is nested butterflies).
This is nothing new, paedophiles have been trying to get themselves seen as a ‘sexual minority’ since the ‘sexual revolution’ at least, but it is particularly pernicious on tumblr, because of the young age range using the site, their lack of critical thinking, and the general environment of looking for the newest oppressed ‘minority’ to support.
We need to remember, paedophiles don’t just groom their victims, they groom their communities as well. I do believe there is such a thing as an ‘ethical paedophile’ (that is, someone who is distressed by their sexual impulses, and does not want to act on them), but ‘ethical paedophiles’ do not hang around on social media trying to get sympathy from children.
