Guru and correction

In the Caitanya Bhagavata, Vrndavan dasa Thakura explains something to this effect. If a disciple commits serious offenses to Vaisnavas, not only does the disciple fall down from devotional service for his offenses, but so does his guru as well (unless that guru is a mahabhagavata). Therefore, it stands to reason that the guru should take the initiative and reject such a bogus disciple before the guru himself must suffer some reaction.

Along these same lines, Prabhupada explains in a purport in CC that if a guru does not teach his disciples how to properly respect other Vaisnavas, he is not a bona fide guru. We can note here that "Vaisnavas" especially means "senior and highly advanced devotees."
