Now that I have your attention, let me explain. My Persian friends are not Muslims, they are Bahá’ís. But, since Bahá’u’lláh stated that Shi’ia (Twelver) Islam is the “true” branch of Islam, I guess that makes them “Twelvers” also.
Then the Twelvers ought not be persecuting the Baha’is, right?
I’ve never heard of that faith expressing that sentiment about Twelver Shi’a Islam. They apparently do not accept that the Mahdi is at the bottom of the Jamkaran mosque’s well waiting to climb out and destroy all unbelievers, from what I read online.
