Take this news for what it is: Gay fans and political groups are approaching Marvel executives and calling out for the very single Captain America to be given a boyfriend. All coming from the same groups that are asking, almost demanding, that Frozen's Elsa be given a girlfriend.
The answer needs to be "No." Back in the day when things were less open, Stan Lee could have made the Captain intentionally sexually ambiguous, but he did not. Let's stay with the original content and honor those who created him. These fans asking for the boyfriend should be ashamed of themselves for wanting to change a classic piece of comic and film art to suit their political agenda.
Will Disney ever make a gay hero or heroine? I'm sure the time will come, but it certainly is not now for this iconic hero.
