What are your opinions re-Iglesia Ni Cristo and their teachings?

While creating alternative religious and historical explanations is interesting, I opine that the Iglesia Ni Cristo has gone about it in an unproductive (to be euphamistic) manner. Attacking other religious institutions while themselves repressing criticisms is rediculous. It is easy to attack the history of the Catholic institution and other religious organizations, but becoming a corrupt intitution while doing it is hypocritical to say the least.
