When your friend tries to get you into a fandom that you don't want to be part of, or tries to tear you away from a fandom that you love, that makes them a pretty shitty friend. Don't surround yourself by people like that. People should be allowed to have interests and to be a part of things without their friends looming over them and ruining their enjoyment. :c
Personally I'd say fuck 'em and stop being friends but not everybody would want to do that, welp.
