The column, which appeared in the Daily Mail, caused outrage on social networking sites and was the subject of 1,000 complaints to the Press Complaints Commission.
In the article, Moir wrote that the events surrounding Gately's death were "sleazy" and contradicted the post-mortem results by suggesting that it was "not, by any yardstick, a natural [death]".
However, Sky News reports that Moir has now defended the column.
"Some people, particularly in the gay community, have been upset by my article about the sad death of Boyzone member Stephen Gately," she said. "That was never my intention.
"Stephen, as I pointed out in the article, was a charming and sweet man who entertained millions.
"However, the point of my column - which I wonder how many of the people complaining have fully read - was to suggest that, in my honest opinion, his death raises many unanswered questions."
