Some weirdo feels emasculated and threatened by Rin so they make threads 24/7 projecting this insecurity onto /a/. It's pathetic but eventually they just become idolmaster threads which are fun.
I'm afraid of all women, I'm just more afraid of Rin than I am of the others.
Basically she is anti-social but still wants to be loved but is too threatening/suspicious to fit in normally. I mean the street police wanted to question her when she was helping a child in public.
>you'll never have a genki loli Rin and a jealous milf Rin
Kill me, dudes.
