Saying that the dominant religion is Christianity is like saying the dominant pop group is whatever the dominant pop group is.
Drivel. The point I've made was about familiar concepts of 'god'.
Religion is and has been for decades a minority interest to the point where there is little interest for what it says about itself. This is why it is now viewed in cultural terms which along with statistics is the chief lens through which
Secularism presently views the world.
This makes secularism itself and individuals more cultural and exposed to passing fads and charismatic individuals.
Irrelevant wittering (and you still don't seem to understand secularism).
In terms of rationality. I believe a moral realism is more rational than an alternative system where moral Stances are made up.
You may find it easier but where is the rational argument that that is the way things are, rather than how you'd like them to be? Who's suggesting that they are just 'made up'.
That it is more reasonable to stick with cause and effect...
Why? We have reasons aplenty to think it doesn't universally apply even within space-time, let alone trying to apply it the space-time itself (where it's actually difficulty to even make it make any sense).
...with prime actualizer...
Why only one and what's the connection to any god?
...than insisting on cause and effect until it doesn't suit.
Which is exactly what postulating a "prime actualizer" would be doing.
These are all reasonable.
Then show your reasoning.
The universe just is....and that is it......is definitionally unreasonable for we are eschewing a reason.
Trying to shift the burden of proof. We don't need to know how or why the universe exists to dismiss your unfounded claims.
