Religion is a net positive on society and this is born out in multiple facets. In "The Anxious Generation" its shown that those who go to church regularly are more fulfilled, happier, and less depressed on average than those in their same age cohort. Religion also gives man a higher principled calling that allows him to not view himself as the center and instead call himself to serve others. Most of the great societies ever were centered around religion, such as Roman, Greece, Western Europe, and many of these societies rely on religion to ground their ethics and morals.

The division is not a coherent argument because if you look at Mao's China or Stalin's USSR, many of the atheistic societies in the modern world have grown and breed division at a bigger and worse rate than religion has for any society. Religion directly led to the ending of slavery in Rome, and America. It also directly led to the protections of widows and orphans

No you are shifting the goalposts again and notice you have made no argument why that is bad for society at large. Control in religion comes from God but control from Mao's China and Stalin's USSR come from the state. Which has born worse fruit? Considering that the USSR fell and all of Western Europe and America are better on most metrics of freedom and happiness I would say its clear who wins this debate.
