This is the exact sort of statement that resulted in that happening in the SU fandom in the first place. They were all “oh no don’t let the bronies in”

then people started trying to police things and bein really mean to anyone they thought was a threat to their perfect fandom.

The easiest (but also not actually possible)way to let a fandom be aight for everyone to just chill and not worry so much about what everyone else does or who else is in it.
