@BillRM,
Your equating the Boy Scouts with the KKK is just absurd. The attempt to associate the two groups is clearly designed to be inflammatory rather than logical. No matter how one feels about the Boy Scouts exclusionary membership policies, or even their stated organizational principles, they are not the equivalent of a virulent hate group with a historical track record of terrorist tactics. Drumming up the images of white-hooded mobs burning crosses, fire-bombing homes, and hanging people from tree limbs, does not serve to advance your argument opposing the Boy Scouts policies, it simply makes you seem like an overly histrionic fool who is trying to persuade through smear tactics rather than reason.
This topic is also disingenuous because, in your opening post, you assume that the Boy Scouts exclusion of atheists and agnostics has received little attention or note. If you are so concerned with this issue, you surely should be aware that considerable litigation and public discussion of this matter has already taken place, and, if you're not aware of that fact, you should acquaint yourself with the court rulings, and public and corporate discussions, and decisions, on the topic ASAP.

Congress has voted, overwhelmingly, in support of continuing the Scouts federal charter, so, grumbling about that to your Senator or Congressional Representative is likely to get you nowhere, particularly in a country that has the word "God" plastered on its money, displayed in its courthouses, and, in the 1950's, inserted it into the Pledge of Allegiance. And, virtually all recent Presidents have ended addresses to the nation by saying, "God bless the United States." The emphasis on the spiritual elements within our secular government is strong, and, therefore, not really at odds with, or inconsistent with, similar spiritual elements in the Boy Scouts formal Statement of Religious Principles. Spirituality is quite distinct from religion, and atheists and agnostics are confronted with government sponsored and endorsed spiritual messages rather constantly, and that has been the case since our country's inception. It is unlikely that these spiritual messages and references to "God" will ever entirely vanish from our government discourse, and non-believers generally learn to live with that because it is part of the fabric of our particular American culture.
Personally, I see a distinct difference between the Boy Scouts discrimination against homosexuals and their exclusion of atheists and agnostics. I see the antipathy toward gays as stemming from interpretations of particular religious beliefs and mind-set, and an attempt to promote morality and conduct which is in line with such religious beliefs, just as is done by many churches--and such beliefs are not intended to be all-embracing or all-accepting . The exclusion of atheists and agnostics, on the other hand, is essentially directed toward those people who are at odds with the basic spiritual core values espoused and promoted by the organization, and, if admitted, such individuals could well have an undesirable, and divisive, and corrosive, influence on the spiritual values which comprise an essential element of the organization's foundation. While I might disagree with both of these policies, I would uphold the right of a private non-profit group to have Freedom of Assembly with members of their own choosing.
In terms of its spiritual elements, I see the Boy Scouts as far more akin to a group like Alcoholics Anonymous, in the sense of promoting, or advocating, belief in some higher power among members, than I do with your attempts to link it to virulent hate groups. And, simply based on its exclusion of atheists and agnostics, without getting into the homosexual issue, I would not necessarily deny the Boy Scouts equal access, with a group like AA, when it comes to the use of public facilities for activities and meetings.
Look, if you don't like the Boy Scouts policies, don't let your children or grandchildren join, don't contribute money to them, don't support or patronize their corporate sponsors, write to your elected representatives protesting the Scouts receipt of any government benefits, and try to support alternative youth organizations with policies more to your liking. Trying to force a private group, with many positives in its favor, to alter its basic spiritual belief structure, and to abandon one of its foundational elements, simply to accommodate those who disagree with, or oppose, its core spiritual values, not only is an unreasonable demand, it reveals your own anti-religious bias and intolerance. Your own intolerance is no better than, or more noble than, or more defensible than, that of the Boy Scouts.
