Opinion bashing

A strange internet neologism of unknown origin. It can be interpreted as "insulting or not respecting someone's opinion", especially when it comes to a piece of children's media. Pretty popular with Goanimate and Deviantart people.

User1: You should not bash my opinion on Shrek 2! Opinion bashing is wrong and you should learn how to handle opinions!
User2: What the fuck are you talking about?
