They will feel shame because this horrible person on the internet who presents themselves as an authority figure has written an essay to shame them. At the risk of sympathy, the poster was reaching-out for validation and got brutally shot-down and they only reason they will feel bad is because BFS has told them they are rejecting all their friends and community. They have been made to feel like it's a choice between themselves and everyone else. It's a really terrible thing to do to someone. Good thing these are all tolerant, accepting, supportive people, right?
