That alone is something you should not ignore - especially considering the Chantry's dogma is directly tied to total conversion of "heretical" peoples and facilitates expansionist attitudes.
It facilitates expansionist attitudes about as much as the Dalish culture facilitates genocide. Possible in theory, advocated by some extremists, absent in practiced policy. It's about as inherent as, oh, the American political motif of spreading freedom and democracy across the world equating world conquest.
Even the point about the total conversion of 'heretical' peoples is overstating it. The Chantry doesn't maintain a policy of mandating conversion and expanding the Chant by conquest of nonbelievers for the purpose of conversion itself- as the Dev's have mentioned before, they've broadly taken the stance that the True Religion will ultimately come on top on its own, without needing to be forced at sword point. The only mass forced-conversion in the history of the setting directed by the Chantry itself was in the creation of the Alienages, and even that comes with the caveat of it being uncleare if the elves were allowed to refuse and join the Dalish exodus. One could argue that the Exalted Marches against Tevinter were an attempt, but it would be ignoring that the religious schism corresponded with the return of the Tevinter mageocracy and its abuses of magic and slavery- as much a political struggle as a religious one.
As it is, there's precious little to support the idea that the Chantry has, say, sent its Templars and might to crush and convert nonbelievers in any systemic or organized fashion. It hasn't happened with the Dwarves, who are already dependent on the surface for trade and losing a war with the Darkspawn, it hasn't happened with the Dalish (who seem to be targeted more because of their mages than religion, and even then only when they remain near settlemetns for long periods), it wasn't happening with the Ferelden Barbarians in the South, it wasn't happening in Rivain, and it wasn't even being discussed towards the Qunari and their sympathizers/converts in Kirkwall. Heck the Andrastian powers outright let their city elves leave the city and join the Dalish, despite the expected conversion to heathen ways.
The Chantry's dogma is interested in the total conversion of the 'heathens', but it isn't and hasn't been cast in terms of urgency and haste justifying and necessitating conversion by the sword. The few who have believed in the urgency of eternity are... pretty much Petrice, who the game pretty much beat you over the head with the fact that hers was a marginalized and deviant viewpoint.
None of which is to say that religious intolerance doesn't occur- it's just not directed or encouraged by the Chantry dogma. It happens at the national or even local level. It doesn't need direction and sanction from the Chantry to happen. The Chantry's stance on heretics in the Dragon Age has been to send missionaries if possible, allow refusal by individuals who don't wish to be part of the faith, and defend the faithful from attack.
