Everyone in the Revolutionary Army is low-key convinced that Dragon resents and dislikes Shanks because of how this random-ass pirate just rocked up to Dragon’s son’s hometown and instantly won his love and admiration and then gave him inspiration for how to live his life while hanging out around the kid for a whole year, while Dragon hasn’t seen Luffy for more than five minutes or been able to spend any time with him since the kid was like, two.
While in reality, Dragon’s opinion of Shanks (which he never actually discusses with anyone because he’s busy and it’s all revolution all the time at the moment) is more along the lines of ‘oh yeah that powerful pirate who really pisses off the WG! He lost his arm saving my kid’s life and inspired Luffy into becoming the massive problem for the world government that he is today! Love that guy!'
