are emos behaving themselves, not stealing or mugging or vandalizing, if so then they really ought to be low on the list of social phenomena to worry about at any official level. let churches preach the gospel to them.
If you remove the widespread STDs, massive drug use, abortion as birth control, petty theft, aborted suicide attempts ‘cutting’ and such, then no, they really cause no problem to society at all.
My daughter, now 22, went to school with lots of early emos. Trust me. It isn’t all cute hair and weird clothing.
