To all people talking about gyarus: have you ever met gyarus IRL? Talked hung out, went to places, spent time together all that jazz?
Because if you didn't, how're you that sure of what they do, what they like, how they are? Mangas portray them in a way yes, but it's a FICTIONAL way that may or may not be realistic. Even the magazine is fictional so reality could be different.
I for one, haven't met one, so I won't think that this or that portrayal is more accurate than the others, and I've seen a lot of them. But because I haven't met one IRL, I don't have references to say is accurate or not.
TL;DR: if you don't know something for certain, maybe it's best if you don't throw opinions so freely in case you make a fool of yourself.
