Answer: He calls it hypocritical bullshit because half breeds exist in both half-demon and half-angel form, they "whisper thoughts" to us that are both positive and negative suggesting that we will do both positive and negative things, confusing us humans. They call it a balance because there are an equal amount of both good and bad half breeds. However he thinks this is unjust, because they should let us make decisions on our own.
