How come there is no RED (THUMBS DOWN) button for DISLIKE a picture or a video just like there's already A GREEN (THUMBS UP) button for LIKE?There should be a choice between LIKE and DISLIKE! Agreed?

Fanpop is intended as a positive place. You're meant to celebrate and share the things you're a fan of, not show dislike.

However, when there was rating before fanning, it was possible to give a low rating (1 or 2 out of 5). I think the negative use of that feature was one of the reasons it got changed.

No need for encouraging hate..
Let us stay positive. Ignore the bad ppl

I think a dislike button, if it existed, would just be misused. There's a difference between disliking content because it's badly made/lacking credit or keywords/claiming someone else's work as your own, and simply disliking content based on its subject. But I'm sure the majority would dislike content just because they dislike the character or pairing or fandom involved.

And as others have pointed out, this place is FANpop. You're meant to focus on what you're a fan of, not what you're not a fan of. In theory just ignoring/not fanning the content you don't like ought to differentiate between it and the stuff which is liked, anyway, because the more positive things out to have more fans, favourites and comments (but that doesn't work in practice because so many clubs are ghost towns or only have one active member).

There is one now, my friend, 3 years later. Well, not one but two buttons, both thumbs up and thumbs down button, only on this modern Fanpop, and none of them is red or green by color. Looks like you got your wish, my friend. Now, everybody can dislike you, or me, simply by hitting that thumbs down button. Hope you're happy now. :-P

I feel like that would cause so much drama. Also YouTube's dislike feature is useless anyways. You can click dislike but it doesn't do anything so idk why they even have it.

Fanpop in particular it would strike me as odd to have a dislike button because it's FANpop. The whole spirit of the site is to like stuff you like not hate on stuff that you don't.

Most of the dislikes I’ve gotten on my YouTube videos have been on the ones where I had a very unpopular opinion about something. And the people who disliked them seldom gave me a reason why (outside of “You’re an idiot to believe that”). If you really dislike or disagree with something explain why. If it’s poorly done tell the person how they can improve. If you disagree with their point of view give your reasons. But in my opinion a dislike button doesn’t do a lot of good.

But to answer your question, I think they’ve decided that having just a ‘like’ button is an effective way of rating content without having to deal with the abuse of a ‘dislike’ button. And, as I said before, people can still express their negative opinions towards content they don’t like.
