Images of anime girls (waifus), unlike other imagery, allow one to instantly tell which posters are Aryan. Allow me to provide some examples.
The following posters are Aryan (good aesthetic taste, handsome in real life):
>>16359934
>>16360724
>>16354880
>>16361273
>>16361112
The following posters are subhuman (deranged aesthetic taste, ugly in real life):
>>16360525
>>16358466
>>16358023
>>16360846
>>16360775

Non-Aryans are both ugly on the outside and ugly on the inside. This means that their aesthetic taste is deeply sick and demented, compared to the beauty of the white mind.
If you belong to the former category, always remember that posters with poor taste in waifu are the kind of people you would not talk to if you saw them in real life -- fat, brown, disrespectful, low IQ, selfish, etc. Aesthetic taste is a litmus test for whether someone is Aryan, which is why waifuposting is critical in knowing who is worth your time replying to. Uglyposters have poor genetics and take pleasure in corrupting anything that is good, including online spaces. Despite being anonymous, posters who are Aryan can identify each other by their aesthetic taste via waifuposting. Always remember that the minds of other people are unfathomable, and do not make the mistake of assuming other people think similarly to how you do. There are many, many, disgusting people out there, and there are many of them on this very board. As the solution to their presence in real life is genocide, the solution to their presence online is shaming and otherwise ignoring.
I believe a lot of people already understand this on an intuitive level, but I wanted to explain it more explicitly.
