Is it just me, or does it seem like nobody seems to care that Anders started to glow right before he blew up the chantry?

You mean like why weren't Meredith and the templars going "HOLY $*!@#! Abomination, abomination!" at that point? Well, these
are the same templars who don't seem to notice a robed and staffed Hawke wandering around shooting fireballs at people in the middle of the Gallows.

Cullen: Mages aren't like you and me.
Hawke: ::juggling fireballs:: You don't say.
Cullen: No way, they're super dangerous. You should tell me if you see any.
Hawke: Merrill, Anders, you guys hear that? We need to keep an eye out for mages
::Merrill and Anders are using their glowing magic staffs to bounce lightning back and forth, Legend of Zelda style::
Merrill: Oh, we'll definitely do that.
Anders: Yeah, sure thing bro. Mages, man. Can't trust 'em.
Cullen: I'm glad you guys agree with me. Ya'll are awesome.
::Hawke uses Cone of Cold::
Cullen: Huh. Does it seem suddenly cold out here to you?
Hawke: Nope
Cullen: Must be my imagination.
