Atheists like myself still obey the scout oath and law.
The scout oath says:
On my honor, I will do my best to do my duty to God and my country
I do my best. My best is that I do not believe there is a God. I think it is a children's story made up to put priests in power by selling people comforting myths and legends. The best I can do is my duty to my country. I pay my taxes. I vote. And I speak out. I volunteer for things. Etc.
Likewise, I also obey the Scout Law:
A Scout is reverent. He is faithful in his religious duties. He respects the beliefs of others.
I am faithful in my religious duties. My religious duties are to wait for solid evidence of an afterlife or supreme being before I believe in one. In the meantime, I spend my time respecting the beliefs of others. Our scout unit has a chaplain. As the unit leader, I ask him to give prayers before eating or at the end of the meeting. I bow my head and remove my hat during prayers. In fact, sometimes I am the one leading the prayers when he is not there. I usually do the Great Scouter of all Scouts prayer, or the Philmont prayer. You religious guys seem to like those, and it seems courteous, kind, and friendly to fulfill my expected role in those areas.
I never speak about religion to boys in the unit. I assume the parents and the fundamentalist church that hired me to lead this unit without asking my religious background would not appreciate me evangelizing for atheism. So, I don't speak of it, and I tell my son to not speak of it to scouting friends.
Should I be kicked out? I don't think so. Should I be allowed to be an atheist openly? Yes. Would I do so openly? No. I would remain secretive about it and continue to lie to people about my religion. I wish I could be trustworthy on the topic, but BSA and the COR's beliefs have placed me in the difficult position of having to lie to maintain my membership. As I teach my sons, "A Scout Is Trustworthy" does not mean that he outs himself as a Jew to Nazis. It just means people can rely on you. So far, this unit has relied on me, and I have delivered.
Without me, this unit dies. I am what holds it together.
I wish religion would go away from the world. I think it is nonsense. But, that will never happen, so I work within the confines that those who still need it require, and it is a sacrifice on my part that you who despise me will never understand or appreciate.
Meanwhile, all around me I listen to people tell me about how atheists cannot be good people, because apparently everyone will murder and steal without religion.
I am a black man before MLK came along in a way. I'm OK with it. One day, religion will start to fizzle as we continue to advance technologically. Just like in Europe. For now, this is us, and I am one of us, so I do my job. I'm the best man for it.
