Some of the reasons why Arya Samaji's and others criticize Hare Krishna's (they call ISKCON, Gaudiya Matha and others who claim to represent Gaudiya Vaisnava's as Hare Krishna's) is that they see things which are not Vedic and not conform sastra, like:
These are some of the critical points made.
I also conclude above on some persons. However, by knowing the Vaisnava philosophy, we should know by now that we are souls, not men or women. We should treat eachother with respect. Check out this page about criticizing. Not all devotees are like this. Also, women are addressed as Mataji's and men are addressed as Prabhuji's. Indeed there may be some sexual attraction between people. This should be solved by following the 4 regulative principles and chanting the Hare Krishna Maha-Mantra.
Does this mean that the Vedic philosophy as explained by the Brahma-Madhva-Gaudiya Vaisnava Sampradaya of which His Divine Grace A.C. Bhaktivedanta Svami Srila Prabhupada is the latest acarya, is wrong? No!!
Please investigate first before accusing. Srila Prabhupada himself said that the sinister movement has infiltrated into ISKCON already in the 60s! Also at the end, he himself said he was poisoned. That's why it is very important to study yourself! You should be familiar with the sastra yourself!! Why are they changing Srila Prabhupada's books? Ever wondered that? Why do these leaders of religious groups warn all followers, sympathisers and visitors not to speak up? Why do they say that if you do that (to speak up against corrupt leaders) it is Vaisnava Aparadha? It is to control you and get your energy, time and money. As a matter of fact, it is Vaisnava Aparadha when you do not speak up against them because they are falsely representing the Gaudiya Vaisnava Sampradaya!
This website is against those, especially Hindu's who call themselves Arya Samaji's because they insult Srila Prabhpada and the Vedic philosophy. This is a grave offense and I consider it my duty to stand up against the pseudo-devotees (fake Hare Krishna devotees, who pretend and misrepresent Srila Prabhupada, currently this is ISKCON and Gaudiya Matha), Mayavadi's, Sunyavadi's, Atheists, Demi-god worshipers and people who call themselves Hindu's like Arya Samaji's.
