Meh - strikes me as a bit of a stretch. Sure, it's possible those two old guys are supposed to be gay - they do seem to be being awfully affectionate - but Hooded Justice and Captain Metropolis? I think that's pushing it - the wikia seems to be basing this conclusion on (mainly) two things: one, that the guy on the right has a mustache like Hooded Justice is supposed to have had, and two, that their bow ties have little white dots like domino masks. Well, yeah, sure, the old guy has a walrus mustache and so (supposedly) did Hooded Justice, but if I remember correctly, Hooded Justice is also supposed to be bald. Whereas the old guy has a full head of hair. As for the 'mask-tie' theory, those dots look more like light catching the folds of the tie than a conscious design.
