Because the organization doesn't. You've accepted a lie. And based on the rest of your post, you've apparently accepted many lies. Support them with facts if you can.
I have accepted no lies. I have gone to their website and spent about 2 days reading the information posted there.
I came away with the distinct impression that what they stand for is exactly what I stated before.
Go read the info for wourself, or better yet provide me with the information that disputes what I claimed.
Yet you offer nothing to back up your claims that the goal of the CFR is "to weaken national sovereignty and push towards the establishment of a North American superstate." Instead, you say "I came away with the distinct impression that what they stand for is exactly what I stated before." Give some specifics of what gave you that impression? You have already questioned why a very broad cross section of some of the most accomplished experts on United States foreign affairs would retain their membership in such an organization. You simply haven't offered any evidence to support the CFR is what you say it is, and among the best evidence to say it isn't is that it retains the members it does.
