I don't find it much of an overreaction at all.

I guess you also have to take it into perspective: While we're somewhat reading from Rin's point of view, where he didn't belive demons existed until recently,

for all the rest of the kids, they've grown up their whole lives living with demons, not to mention Satan's killed members of their families, so to them Satan is the most evil, terrifying demon, and to suddenly find out that their classmate is Satan's son is a huge shock.
