:What's the Deal, Vocaloid Fans?:

So I go on Youtube and look up I=Fantasy, and I visit the SBS Official Demo, the one where she's singing and there's the 3D model etc.

This one person makes a comment about how Miku fans should lay off and not talk about her being better than SeeU on SeeU's videos, and if they want to talk about Miku, do it on Miku's videos. Then this massive Miku fan comes up and starts talking about how Miku is the best and blah blah blah, and the person defending SeeU ends up getting down voted, and the Miku fan ends up getting up voted.

HOW DOES THAT WORK??

She was just defending SeeU, from what I could tell. I think she's also responded to the Miku fan again, but I haven't checked.
There were also a lot of comments which were removed in response to SeeU defender lady's comment...so idk.

But seriously? How can people be allowed to talk bad about SeeU or how Miku's so much better on SeeU's own videos, but people defending her get negative votes? Like what?

Can anyone explain that to me? :1
