In one relatively minor way, we can easily see how pervasive and harmful this attitude is. Just look at the Boyscouts of America, currently rebranding as Scouting America as they open up their ranks to queer people, women, and girls.

The organization seems dedicated to true inclusivity.

Except for one class of people: atheists, who are not welcome in scouting either as children or adults.

Explicitly.

And in common actual practice.
