The claim is:<quoted text> Belief is irrelevant the CLAIM is fallacious , genius.
"There exists a religion which is based around this deity."
Show me where that claim is fallacious.
It's NOT. Religions DO exist. They've existed in the past. They exist in the present. They will likely exist well into the future.
The fact that you personally disagree with a current or past religion has NO BEARING on whether or not that religion exists.
In fact, you CAN'T disagree with it if it DIDN'T exist.
Your entire complain demonstrates that these religions do in fact exist.
Your argument is moot
