Two things have put me in despair:

One: the logical evolution of the ore no yome fad through that "marry a manga character" petition. You've probably seen this link flying around the Internet, no need for me to reproduce it.

Two, and this one really takes the cake: The niece porn game (in case the "porn game" part doesn't tip you off, let me remind you that this link is totally Not Safe for Work).

I'm in despair! I'm in despair because Japan has gone too far!
（絶望した！やり過ぎた日本に絶望した！）
