There was also a time when Superman wasn't broken apparently. Get with the times already. Face rubbing stopped when yukkuris stopped being portrayed as innocent and benign.
Donut, you just don't get it do you? Yukkuris are different for every person and artist. For some artists they are cute and funny, and to others they are disgusting pests. If it helps some artists get off by drawing sexual organs on disfigured heads then so be it, but that doesn't mean penipenis and mamumamus should forever be accepted by everyone. Accepting whatever the community craps comes second to artistic creativity.
^The point of YukkuSutra is to hammer home the fact that these creatures are utterly disgusting. But for those who like to thing that Yukkuri are cuties, there are Makako's pics. Also, what the hell? What happened to Marisa's braggable penipeni? Bah.
I get it...I get that some people actually think they're cute, and they're entitled to that. However, the vast majority of the yukkuri community has moved on from face rubbing and stuff like that, and you have to accept it.
Honestly, I never thought yukkuris were remotely cute in the first place, even before I knew more about them.
