what is the greatest hyprocrisy of humanity?

Christianity

Saying that everyone is allowed to loved and believe as they choose then trying to convince them that they are wrong and we are right when we do not agree with them.

I think the greates hypocrisy of humanity is judgements. I think that everyone wants to say do not judge others, but people do. I mean even christians, they sy dont judge but then shun the sinner because they disagreewith their actions, when it should be hate the sin love the sinner, but that is just my opinion.

I think it is POLYTHEISM,which is also the only unforgivable and most heinous sin in the last Holy Book........It is also the deadliest sin in Islam.
