Somebody made a living generating and promulgating those ideas. They have university chairmanships, publish books, and speak at conferences.
If those kids want to make a difference they should be doing it as red, white, and blue United States citizens. That is the only acceptable religion to associate with one's civic duty.
There is a saying in psychology circles that goes, "you can't tell people how they feel". Any number of studies seem to indicate that the more strongly someone feels about something the more they dig in their heels to defend their beliefs then presented with contrary evidence. Faith and religion are emotional experiences and any organization that becomes the facilitator of that experience has considerable control over its followers. It's very difficult to separate oneself from that control - and that dynamic is the same for religious belief and simple brand loyalty. The most unscrupulous religions are those who most exploit the latter, and in a capitalist society any organization has to depend on the profit motive at least a little. The emotional bonds we create with shared ideas, including the profit motive, are at the root of all human civilization and has ensured the survival - and tragedy - of our species.
The latest and best effort to foster cooperation and support among groups of people has been a nationalist form of government, which replaced religion in that role. The transition has been a barbaric and bloody one. And it will never be complete if we allow civic activity defined by faith in anything other than ourselves.
Having said all that, I'm sure those kids will do just fine. There is a big difference between a specific situation and an overall cultural trend. I'm the first to admit that I don't know how to parse the role of religion in government - because I can't tell people how they feel. But I know people are only human and I don't think there's any reason to believe any religious organization or leader will judiciously exercise the considerable power that the faith of believers will give them. I haven't seen one succeed yet.
