Before answering this claim, we should know the meaning of the independent investigation of truth:

     The independent investigation of truth means searching for truth; that is, everybody himself/herself should search for truth to find it through thought and attempt.

     Now, we should investigate this issue that is there any independent investigation of truth in Baha’ism?!!!

1)   The Baha’i kids are subject to condensed educational programs of the Baha’ism organization by adolescence; so that, they have no choice but Baha’ism for them. Kids must participate at Golestan Towhid classes before elementary school and it is obligatory for all families.

2)  The real being blind and deaf in Baha’ism means nobody is allowed to deduce except what is said by the Universal House of Justice. (Will tablets, p. 13)

3)  Everybody who gains reality and turns against Baha’ism and turns to Islam must be excommunicated spiritually (Toqia’t Mobarekeh [the Blessed writings], p. 42)/ in this punishment, an excommunicated person must be thrown away like rubbish and nobody, even intimates, is allowed to have social intercourses with him/her.
