Sorry Myss... But like you, everyone is entitled to their own opinions. Sure it disgusts you, but have you ran into people who do it for attention? Or do it to make friends?
Have you had friends constantly making jokes about "emo" kids and telling them to go cut their wrists, not knowing that you struggle yourself? If you have, then you know how it can be offensive and how it makes it so much harder to find help when you need it.
Although I agree with you when you have said that there is a good reason why they do it... you also have to realize that SOME, I repeat SOME, of the over the top "hxc emo" tagging
sh-ers make it more difficult for those that do it to cope. I don't mean any offence to you, but you want people to see how you see it, but I feel as if you haven't been looking from everyone else's angle. Sure we're all here to share opinions and the such, but you should also respect other's.
