There are several major problems with what you just said.
First is the idea that nonbelievers will naturally be more inclined to immorality, or that society can't exist without a "scaffold of morality that is constructed of faith and held together by religion." This is empirically disproved by the examples of nations like Denmark and Sweden where the majority of the nation is secular and they enjoy more stability than most religious nations, including America.
Second is the idea that it's valid to build a moral code around fiction. If there is no God, any theistic moral code is simply an arbitrary construct built around a convenient concept. There's no guarantee that this kind of moral code will provide good moral standards - just a moral standard. Why not just excise the good moral concepts from the supernatural nonsense and the hordes of bad moral concepts (e.g., stoning homosexuals, enslaving foreigners, killing purported witches, etc.)? Not to mention that such a system, based on fiction, would be without grounds to say that dishonesty is immoral, seeing how it would require massive amounts of dishonesty just to assert an absolute source for the moral code.
Third, there is no real-world benefit that a religious moral system can provide that a secular one can't. None. However, there are many damaging things that organized religions have promoted that couldn't be justified by a secular system. The indoctrination of children with incredible amounts of false information, for example, or religiously-motivated bigotry, or holy wars, or any number of other things that spring quickly to mind.
Fourth, you seem to be implying that the solution to intellectual laziness is dishonesty. If people aren't willing to think things through, you're saying it's better to lie to them about the reason something is right or wrong than to give them a reason to think about it.
A moral system based on organized religion, when there is no god, is simply an arbitrary set of rules. Many of these rules would necessarily involve performing the will of a nonexistent being, and lying to the people who are too intellectually lazy to think things through. There are no benefits to such a system that couldn't be gained without the lies.
