I don’t think you need to add nosyonos for the sake of it; there are plenty already.
That said, some communities are sheltered to the point that their members can’t function in the world.
We were meant to make a positive impact on the world. I am not a chabadnick, but I laud the way they fearlessly reach out to chilonim and even gentiles to make the world a better place. And they do it with positivity, not fear mongering. The chabad young men and women who stay on the derech do it out of free will, not because the are trapped by ignorance of the real world.
