who was the winx that hated the w.i.t.c.h?

no one of the winx hated the winx and no w.i.t.c.h hated the winx
the one who started this war where the fans of both shows

None of them, the winx and the w.i.t.c.h. girls live in entirly diffrent shows and have never come in contact with eachother thus none of the winx hate any of the w.i.t.c.h. girls.

Stella i guess, she likes criticism...

This is a silly question. They're characters from different fictional worlds, my friend.
