What the hell are you talking about?
The article has nothing to do with Card's homophobia. It wasn't even triggered by one of his anti-gay rants. The article came out about the time Card was demanding the press be punished for reporting truthfully on abuses by the American government during the War on Terror.
And, FWIW, your attack on the article doesn't even make sense, it certainly doesn't suggest you read it. The author isn't attacking Card for making Ender Hitler, he's merely referencing what happened when someone else made that claim.
The author's suggestion is that Card probably never wrote the first two Enders Games novels. He draws this conclusion based upon Card's response to the claim that Ender is Hitler - namely that Card didn't appear to know what was in his own novel, denying the novel contained elements even given references, and the massive quality change that occured between the second and third novels - as well as the substantial delay in publication.
Is that a reasonable conclusion? I don't know, it sounds to me more like Card has difficulty coping with criticism, and the third novel could easily be bad because he's, ultimately, a hack who got lucky with his first. But it certainly isn't a conclusion drawn by someone trying to explain why Card's homophobic, or more generally, a fascist.
