The primary cause ( note the word: primary) for conflict amongst humans is the lust for power and greed, very much a human condition/ construct. Religion has been used as an excuse. There are many examples, I’ll proffer the Mongol expansion throughout Asia, Eurasia and Europe as one as it was pretty horrific. As far as historians understand, their primary motive was to secure trade rights.
I do wonder if the most zealous atheist posters here are in some ways rather like the shouty homophobes one encounters, in so far as their fear of being actually what they publicly despise helps with their self denial? I’ll put a wink in here, just because I can. 😉
And for those who choose to live their lives on a binary yes/no, proven fact or not basis, wow! Each to their own, but I like the grey areas, the unknowns, the hypothesis, the looking into the night sky and knowing that the observer changes the reality and that really, we know **** all.
I’ll return to this thread this evening, it might have been closed by then, so a gentle reminder for those that probably won’t read ( or understand) this bit, that dogmatism isn’t a virtue, there’s no need to be a pillock about it.
