The last also happens in the absence of religious motivation quite a bit.

For real. Literally you can just say, "You are the problem. All girls and women are the problem." There's zero need to bring God into the equation to live a good, normal life.

It's a sarcastic counter to the typical arguments that there's no inherent morality in human culture without religion. You know, people don't naturally have empathy, so they have to be taught to simulate empathy because they beleive they'll be judged when they die.

Generally in atheistic communities discourse around religion tends to be around where religion is used to replace science, often as a means of control of behavior and othering of out groups.

Speculating, that is likely because many people join these communities after being ostracized or faced abuse at the hands of people in the in-group so it makes sense that those are the aspects of religion that stand out most to them are those aspects.

There is a reason communities have had religious and spiritual practices for millennia, they do provide concrete benefits and social good in terms of community building and as forms of cultural preservation and providing support systems, both emotional and material. Those aspects tend not to be talked about in atheistic and skeptic communities. Not saying they're obligated to balance every negative comment with a positive one out of some misguided sense of fairness or balanced discourse but if you're interested in having some kind of well rounded view of the world, it is helpful to understand positive aspects of things you generally disagree with.

In this case, if someone is arguing religion be removed completely it is important to address the loss of positive aspects that keep people in a religion otherwise you're just going to be yelling at a wall and not actually doing anything or putting people off by assuming everyone who holds any kind of religious belief or engages in religious rituals is some kind of brainwashed cultist.
