I originally typed ‘Arguably the worst thing we’ve done’ but the more I think on it, humans are generally terrible.

If it wasn’t religion, it’d be racism, sexisim, geography based hate, abilisim, left handedness, phrenology, etc etc etc. Religion is just another lubricant to placate docile individuals, and justify the actions of hate focused individuals

I’m certain we could all live together in peace, but we’re so tribalistic that the second anyone says their group is better than X because Y the majority of the population seems to lap it up at nearly any expense.
