I determine false religions/beliefs using the following guide;
1) Do people forge evidence for the sake of the belief? If this is true then it is a false religion.
2) Do the proponents of the religion undermine your beliefs by stating that you have no evidence for your beliefs. If they do this their religion is a false one.
3) Do the proponents of the belief state that you are either ignorant, stupid, insane or wicked if you choose not to follow them? If they do this their religion is a false one.
4) Do the believers think that your God is a cruel and evil God. If they believe this then theirs is a false religion.
5) Does the proponent of the belief promote and evangelise his belief willingly or does he engage in negative tactics such as witholding information, not engaging and belittling his opponents.
If he engages in negative tactics it is a false religion.
