Why do some many people like yaoi?

because some of the やおい couples are actually real while others are made up and really stupid, for example, Sensui and Itsuki from Yu Yu Hakusho are practically together because Itsuki 発言しました he wanted to be Sensui's lover and stupid made up ones are Sora and Roxas, Kurama and Hiei, and Lee and Gaara. Most times, やおい couples are extremely retarded because they're 2 ppl tht hate each other. For example, Marluxia and Vexen marluxia wanted vexen killed, they hate each other and ppl put them together all the time. Lee x Gaara is really stupid because Gaara almost killed Lee...reason to put together...NONE. Another reason i hate about most やおい couples is tht theyre guys who already have girlfriends but ppl still put them together. So yeah, most やおい is really stupid, but there are a few tht i like.

It's called fangirls. They make it popular.

Because everyone has their own opinion... They like it because they do. It's just their "taste" in anime/manga.

Because one hot アニメ guy is good, but two are better :3 Especially in the case of yaoi, where 発言しました hot アニメ guys are shirtless on a regular basis.

Basically: Fangirls like getting nosebleeds for some reason.

because everyone has different taste....DUH!!!
btw i dont like yaoi, yuri または hentai... however soujo in acceptable on my preference of scale...

Because just like any genre of shows, it has fans.
Simple as that :)

Yaoi? Why do so many people like yaoi?!
*insert laugh here*
Oh あなた silly, silly アニメ fan!
やおい is the answer to all of life's problem-no I'm just joking.
Fangirls...oh the fangirls and how they obsess Dx.
It's terrifying!

the same reason why most people like NARUTO -ナルト- and death note and most people don't everybody likes different things....!! think!!!!!!!:]
