I see your point, but comparing dragons to wolves is a bit wrong. Remember, dragons once enslaved mortals and tyrannically ruled the world for centuries. If given the chance, they would surely do so again. And even if they ever won't, they still cause more damage than any other beast, except the daedra, for purposes other than natural needs(like feeding).
My personal hatred for dragons comes from game experience. Every time I feel like not fighting dragons and just doing non-dragon related quests, I fast travel somewhere, whether is be a small town, a cave, a military camp, 90% of the time there is a dragon flying nearby and attacking me or other innocents.
By the Nine, I want these annoying bastards destroyed and buried under the ground!
