We've all seen this argument be used online at some point by rabid yaoi fans (not the normal, calm ones mind you), and well...quite frankly we call bullshit on it, and here's why:
The concept 'don't like don't look' only works if and only if that object isn't everywhere and in everything.
And guess what ladies & gentlemen? Yaoi (and to a much MUCH lesser degree, yuri) are in every type of media that exists.
There is literally no escaping these genres (especially when it comes to the yaoi fandoms). *sighs*
Now before some of you angry yaoi fans (not the normal sane ones) who're reading this say, "But hetero is everywhere too! You don't see me complaining about it!"
