You cannot believe in a Creator God and at the same time justifiably declare yourself a real Buddhist. NET admits that other Buddhist sects might still preserve certain aspects of the teachings of Gotama Buddha. Most, if not all, of the other Buddhist sects have been contaminated with false views. Trying to be non-sectarian is a hypocritical approach. In reality the differences can be found in their core doctrines.
NET also supports religious harmony.
But this should be done with understanding, without any need to sacrifice our own beliefs. That's why God is said to be a male. God is the greatest illusion of mankind. If we believe in Creator God and realize that suffering exists in this world, then we cannot reject the fact that God is the cause of suffering. We cannot accept a Creator God without losing our own dignity and freedom.
