The templars answer to the Chantry. Either target is surrounded by the chantry's human shields (mages and chantry initiates/hightown) so to say one would be a "better" target (conveniently, the one full of mages) is silly. And you can ascribe whatever motives you want, but it's not because it targets civilians, because it doesn't, and it's not because it uses terror to coerce demands, because it doesn't. It uses violence to achieve an end- terror and civilian casualties are side effects. That being said, violence to achieve an end when that end is opposed to your own will be called terrorism regardless of the distinctions.
Anders is not using violence to achieve any ends. Killing Elthina, by itself, achieves nothing. The mages won't be free but neither will them be condemned had Meredith been a little more sane.
Had Anders targeted the largest concentration of templars possible and then flooded the city with apostates who would then kill the remaining templars plus the city guard and extablish a free mage state, then Anders would have been using violence to achieve his ends.
Killing Elthina exacerbates the already widespread fear of mages which is what Anders intended "Give them freedom or give them death". The violence used thereafter was used by people who had no relation whatsoever with Anders.
Thus, Anders use terror to achieve a social change which makes him a terrorist.
