You know, I was thinking about it, and the only common element between all monkeyfuckers is awful writing.
They come from all walks of life, from various places, but what they all have in common is an inability to communicate coherently. A lot of them are ESLs that talk in broken English, but even the ones living in the Anglo-sphere talk like retards. You see that in YouTube comments, in /pity/, in VidLii, in various imageboards, everywhere.
Are they actually autistic? Yes obviously a lot of them are, just look at the dox. It might also be that the coom has infiltrated and completely devoured their brains - they type just like coomers type in the comment sections of porn sites.
I can't even give some of them a break for being ESL - a lot of them are adults that come from Western, first-world countries - they should be able to write at least the basics in non-broken English.
My uneducated guess is that they all have some sort of mental deficiency.
Anyone else notice that?
