I don't know much about emo, though i do have good friends who are in to what appears to be 'proper' emo, as in emotional hardcore and so forth. This does, however, appear to be roughly similiar to the thread that happens on every metal forum once a month or so, you know, when DaniFilth195 says Cradle of Filth are his favourite metal band, and Lord Chronos the Unwholesome reads the riot act on the Norwegian first wave, only for Krzgaflknoktzalackack to sneer that only the first Mayhem demo possesed the true blackflame of Satan, and for the whole topic to degenerate into a huge wank session about who has the most Les Legiones Noires vinyl.
People aren't that different, really.
