Exactly what it sounds like. If you have an opinion that everyone else seems to disagree with, post it here and don't get backlash from expressing yourself.
I have a few unpopular opinions:

The Hunger Games sucks balls.
Pokémon Red and Blue (AKA Gen 1) were horrible.
Flash Sentry and FlashLight are fucking awesome.
Shortskirtsandexplosions is a bad writer.
The Beatles are awful.
Pinkie Pie needs to get raped with a loaded gun.
Sonic Generations was actually pretty good.
People who say "No one cares" whenever someone says anything about their religion are better off banned from all social media.
Dropbear (that one changeling fan who seems to be loved by every other changeling fan) is a disgrace to the changeling fanbase.
My Little Dashie is absolute shit, and anyone who likes it wouldn't know a good story if one came up to them and slapped them in the face.

4167248 The CMC must not get their cutie marks in season 5. They must save it for one of the final episodes of the final season. When the CMC get their marks FIM has jumped the shark.

4167277 The two-part season premiere is called "Cutie Markless"...This can either go amazing or horribly.

Edit: LOL never mind I'm stupid!
