I understand your frustrations with the /jp/ community OP, and in fact, I also have a confession to make:
I become deeply upset when people here post - or even just allude to - Touhou pornography. The Touhou project has been a major part of my life. It has helped me through difficult times, has shaped my life philosophy, and has done far more for me than other people ever have. I view the characters not as friends or acquaintances - we have, after all, never met - but instead almost as a part of me.
Thus, to see them reduced to mere objects to serve your bodily lust is nothing short of a travesty. I am usually reasonably good at empathy, but such an act simply stirs my emotions too much for me to be able to "live and let live" or anything similar. The best I can do is ignore it, and that isn't much of a solution - especially when it is waved in front of my face by fellow posters here.
I hate that I am posting this, because I know that people reading this who have sexualised Touhou may feel unnecessarily guilty for my sake. Well, an open message to anyone reading this: if you care even slightly about my plight, please, I beg of you, don't post anything here related to Touhou pornography, and don't encourage or respond to others who do. I've no doubt there are plenty of other places on the internet far away from the eyes of overly sensitive fools such as myself.
