Why did they create the dislike button? If you don't like something just ignore it. Don't give them the satisfaction of saying you don't like it. This may be just my thought/opinion, but I don't see a purpose in posting hate comments on bad things/disliking bad things.
[Also, BTW [which is kind of contradictory of me so my bad], I'm not expecting positive feedback on this thought so if you wanna hate, go ahead. I can't say not to dislike something simply because of everyone's freedom of speech.]
