Okay, let's debate logic vs sympathy.
Mages lash out from a few bad apples, they go to extremes as an outcry rather than trying to reason with them.
Rather than be rational, they submit to power and become a weapon- a tool of the demons rather than try be diplomatic.
Templars might be dickish at times, but that isn't every templar you encountered, in fact there are way more cool Templars you will meet that are level headed and try to accommodate to acctully making things stress free. What do the mages do? They shit all over them simply because of what a few others do, and it isn't just "one" mage, they all collectivly decide to say fuck everything rather than try to use reason, and this forces Templars to disable them because they rather use their power to destroy rather then (again) submit to reason.
It is hard to be rational when your first choice is "Attack the Templars and then make others pity me with oppression, yet my first choice is to kill if it means I can be on the run and be a continuous danger." So yeah.
Do you have a counter argument?
