Corsairs are allied to Hogosha/FA (main distributors of artifacts), one of the key enemies of the Dragons, so I should think tensions would ensue.
However, being enemies does not mean you have to hate the other side 24/7. We're all humans in Sirius (except for those blue, squishy types...), and there's no reason that pilots from opposing factions should not enjoy a drink together on a neutral station...but, remember that you've still got to shoot him in space...
