:Runciman is respected but a little quaint nowadays; he probably thought Humphrey was gay but was too coy to say that directly. I would say it is not really disputed at all one way or the other, in the sense it is not an important question. Everyone seems to agree that he didn't like fighting or disputes of any sort, and that he was very devoted to Isabella, but everyone has different reasons for this, depending on whose side they are on.
