Someone made a video about Toxic fandoms....

And the comments were talking about how they didn't mention Undertale of FNAF....

This is my experience with some fandoms:

FNAF: *arguing about the lore*

Undertale: Um..... People ranting about them. Apparently. 

Evillious Chronicles: WTF DID MOTHY DO WE ARE CONFUSED ALSO GAST IS BAE

Fire Emblem: *husbando fight*

Smash Bros: Generally friendly from what I see.

Servamp: Basically dead with the exception of a few fans

Arrowverse: *fight between ships*

Attack on Titan: I think everyone left. Also, Levi x Eren

Kid Icarus: What is this game you speak of?

Final Fantasy: NOCTIS IS AWESOME.

What about you guys? Any interesting experiences with fandoms?
