Atheist mocking is hypocritical in itself as they have no basis to distinguish right from wrong. Any attempt to have them use logic to prove they are right is an attempt to get them to actually have an intelligent conversation about what they believe which, of course, they are totally clueless.
While it is futile without the leadership of the HS, there is no reason to allow them to only take potshots at the truth while not having to defend their own beliefs. Here is how to get them to think about their hypocrisy.
Atheist means that there can't be a Creator. It is therefore, an admission that there was not intelligent thought to our creation.
Therefore, we have no reason to live and have no purpose. Without a purpose, it is impossible to say what is right and wrong.
Simple....but they don't get it.
How this helps
EDIT
Sage: ***Why would they? The jews do not attack them!!*** That is because so many Reform Jews are atheists. Perhaps it is pity because when Jews don't believe that the Torah records historical events, then:
1. Jews trace their lineage to story book characters
2. God never made a covenant so they have no real claim to Israel or Jerusalem.
Sage: ***Ask yourself why it is only Christians that get attacked and not the other religions?!!!!***
Dude, you really need to go to a Holocaust museum sometime or ask when was the last time the children of Israel remember the God of Israel do anything on their behalf. Check out Rabbinic Jewish history from then to the present.
