Although the followers of Baha’ism claim that there is no difference among humankind and everybody is free to seek and ask their beliefs and there isn’t any limitation for investigation and everybody can change his/her religion every time s/he likes, the first leader of Baha’ism has forbidden speaking with those who have turned against Baha’ism.
It is interesting to be noted that he considers the Shiite Muslims as atheists.
How is it possible for Baha’is to speak and claim about the oneness of humane world?
