Saying ‘this didn’t work for me’ isn’t hate.
Saying ‘I didn’t buy the relationship’ isn’t hate.
Saying ‘This part worked for me but this didn’t’ isn’t hate.
Not liking something isn’t a crime, isn’t hate, and won’t get your fandom card revoked. I promise. Saying certainly isn’t wrong either. There is a very pervasive culture to not critique in fandom because it is a gift culture and saying no to a gift or complaining about it, especially in the USian culture I grew up in, simply isn’t done.
Online fandom is not that, folks. It is perfectly okay to not like something and say you don’t like it. We engage in critique of popular culture by writing fanfiction, creating fan art and writing meta. Responding to fanworks is just another form of interacting with that.
I have been in fandom for a very long time now (let’s just say BSG, the original, was on the air) and I see this every so often. Please, just step away from the keyboard for a day or two and think about if you are going to remember this is a week, month or year (I bet you won’t).
Someone not liking the same things as you IS OKAY. SAYING IT IS OKAY.
