Well, it is the part where society as a whole shuns the awkward. Society doesn't take much notice of the awkward.
Ya ... that's kind of the essence of the shunning. It's a social rejection. While not as blatant as other ways groups are shunned, that doesn't make it any less painful for the people on the receiving end of it who are ignored, overlooked and dismissed. They want to fit in and become part of the groups around them but ... just can't quite make it work. The people they try to associate with either don't pay attention to them or just derisively snicker at their ham-fisted attempts to try and do what everyone else is doing so easily and they just end up alone not really getting why they can't manage to be as much a part of things as the rest of the people they see. It hurts and the pain they feel from it is a real thing.
The dismissive bullshit about how it somehow doesn't matter because you can point to other groups of people who have it worse off is just ... bullshit.
