oh god i've been through this before but i see where you are deriving ur information from. and i shall contradict them because i'm a Kurama fangirl and can support him.
1. Kuronue and Youko were like brothers. You'd grieve too if ur brother was killed for the sake of saving you. Sure, Kurama does grieve for him. But where in the anime do you see it mentioned? it ish only mentioned in the movie and that's only because he was reminded of it. Kurama has supressed that memory, along with all the other ones he's had as a youko so that he could live a normal like as a 'human.'
2. it ish not mysterious reasons why Kurama and Maya broke up. Kurama didnt want to put her in any danger so he erased her memory of ever having met him or her feelings towards him. It's all for her protection, seeing as how he's a demon and may always be trailed or sought after.
Just because someone has long hair doesnt make them gay. My boyfriend has long hair and he's not gay. One of my friends has long hair and he's not gay. That's just a dumb stereotype.
3. Flowers show his elegance. He may be a bit more elegant than your typical manly badass boy but that doesnt prove a thing. Plus, if you ever examine a rose, they can be dangerous. dude...thorns hurt. I mean really.
4. i see...pictures. First one isnt queer at all. It's nice.
second one: they are partners after all so they would watch each other's back.
same goes for the third one.
now the fourth one, i'll give you that one. It ish a bit odd. But that could mean that he and Hiei are close since they are partners and all.
That gay shirt...well...that's ur opinion. I personally find it attractive.
Give Kurama a break dude. He doesnt dance that often, if any at all. And if you see Hiei, he cant dance for beans. Same with the Kuwabara one. Disco? seriously. So if you are gonna look at the dancing pictures, first examine the others.
the Kurama and Yuusuke one ish cropped. It's fanmade. that ish not official.
there. i have contradicted every one of ur points. My apologies for my analysis but i feel it ish my duty as one in love with Kurama to defend him and his being.
