I used to take Cole and Vivienne out in the same party hoping to see Vivienne get frustrated and upset exactly like that, but eventually I stopped because it seemed to only result in poor Cole receiving verbal abuse from her, what with referring to him as a pet and an "it" and such. Glad to see evidence that it really was getting to her.
Wonderful isnt, it?
How he can dredge up horrors like walking through the place you're responsible for, seeing the mangled corpses of your charges and knowing that they were brutally murdered by their fellow mages simply for having a different ideology and wanting to stay in the towers. And then he can put your trauma on display for everyone else to see too.

My thoughts precisely. The moment Leliana reforms the chantry mages are enjoying unprecedented acceptance throughout Thedas.
And it will disappear as soon as the neighbor girl accidentally freezes her entire family to death while arguing with her dad about curfew.
The Chantry isn't responsible for the fear and hate of magic.
Magic is responsible.
Pretty words and impassioned speeches might sway people's hearts for a time, but as soon as people start having to deal with the problems magic causes, that fear will return. The worst thing about Leliana as Divine is that she's the only one capable of truly changing the tide of public opinion, but that goodwill is
wasted in the absence of any methods to deal with magical threats or ensure the safety and schooling of young mages. The new mage college does not have the money or manpower to effectively see to those issues across nations. The Chantry is in every city and village, the mages can't be. So when magical troubles appear, and they
will, there won't be anyone in a position to do anything about it.
There's your "For the moment." qualifier.
If we are looking at the mage-templar approach or invitation rationally, one will end up approaching the mages over the templars.
[...]
Unless you are playing as a Chantry Loyalist or someone who has a phobia towards magic, there is very little reason to take the Templar path.
You also have the option of simply believing Cullen and thinking that unknown magic + unknown magic could have nasty repercussions and the people who can nullify magic instead are the safer choice.
The game does lead you towards the mages, but there are compelling reasons for an Inquisitor to choose the templars anyway.
Even if the Inquisitor wants to help with the mage situation, as TK said, you may still want to seek a templar alliance first. It's very easy to imagine the Inquisitor getting to Redcliffe, realizing she's out of her depth and heading for the templars hoping for assistance with the Breach and dealing with Redcliffe. Of course she has no way of knowing that by then it will be too late.
