IN all fairness, the show makes a good point in that people won`t start to "un-emo" if everyone just kicks them around and won`t help them.
To Un-"emo" someone, you need to reach out to them with kindness. Even Kamina did this with Simon, he never made fun of him to straighten him out, he showed him through example and had confidence in his ability.(this happened again with Nia aroudn episode 12, when everyone thought that leaving simon alone would make him better, it was Nia who knew he had to be reached out to with kind but strong worRAB to get him out of it)
So, if one truly dislikes the existence of "emo", the most logical thing one should do is, help them, not deepen their "emoness" by giving them more of what they've always had.
