We can only parody, satirize, poke fun at or generally mock what is not true at it’s core; because humour is about revealing our individual and collective cognitive dissonance.
Which is why religion is an easy target and blasphemy is just another magnitude of the parody.
The distance between reality – that which we observe and does not change when other people observe it – and our perception of that reality; is where humour lives.
So humour, is a means to divide between those of us who see the gap between reality and perspective and those who do not.
There is no religion that can’t be poked fun at and parodied – but increasingly, religious leaders are so unaware of their cognitive dissonance that their own words or actions draw such attention to the cognitive dissonance that parody isn’t even possible. All you can do is copy what is self-parody.
So, I think that the real difference between an atheist and a theist, is not one god.
But rather, a willingness to be mocked.
Theists are in an abusive relationship with their deity, so it only makes sense that abuse is what makes them comfortable. It’s why they hold beliefs that are easily mockable and why they lash out violently against everyone who differs from them.
They think that abuse is the only way to interact with people and that masochism is the human condition.
Atheists, do not accept being mocked, and there is no way to mock a non-opinion. Atheists do not accept claims for a deity.
This is not the same as denying, because denial means there’s room for there to be a god. Anyone’s opinion or belief can be wrong. Which is why atheism is a non-opinion and non-belief. It’s simple a position of not having enough information to form an opinion either way.
Until there’s evidence for a deity – any deity – there is simply no reason to live your life as if there is one. And no reason to characterize anyone or any group as being immoral, childish, stupid or other things; or denying rights and freedoms, for not accepting unproven claims for a given deity.
