This thread is definitely not worthless and it would be disingenuous to suggest that.
If a point is invalid, it will be exposed as such. If it is valid it's only beneficial to have it reaffirmed. That's why debates like this are important.
What kept us in a cult was a suppression of critical thinking. Threads like this show how important it is that we not only know what we believe but why we believe it.
Believing in things without evidence or pretending to know things we don't know is an unreliable method to base our knowledge and by extension our lives on. So many better choices can be made, and so much more quality can be brought into our lives too, by an evidence-based worldview and reason.
This is the best way to advance our species and our world.
