Okay, why the heck does everybody want the ability to see downvotes on an image?! It's not a good idea AT ALL.
If you could see downvotes, then it would probably be very discouraging if you posted a meme, but then saw that it had only 4 upvotes but 10 downvotes. It would lower your self-esteem quite a bit, and in extreme cases it could cause a user to go inactive or even delete their account.
So please stop suggesting seeing downvotes on a meme! All that feature will do is lower self-esteem and make users feel like their memes are garbage.
(P.S. I am also totally fine with YouTube removing the ability to see dislikes)
