let him do it, dont give him much attention. that really isnt hurting anybody. if he isnt pushing an (anti)religious agenda, i don't care.
Are you joking? It is obvious he is fighting a war against G-d... And to say that he isn't hurting anyone is false, the attention he has gotten has already caused many people to take his apostasy seriously. The whole concept of considering his false fantasy world a religion sets a very dangerous precedent.
A) Spaghetti was invented by man.
B) To say that you are against creationism means that you think everything happened due to random mutation.
C) Spaghetti will never be created through random mutation.
Maybe you believe that there could be a spaghetti monster deity in some alternate universe... But it stands in stark contrast to the firm belief of Jews that there is ONLY ONE G-D and he rules all the worlds... He created everything including time, space, and matter. He even created all sensation and ideas...
Another point is that his religion is obviously a form of Idolatry... And to a Jew this is the ultimate insult to our G-d...
