Did you read the accusation in the article made by the author or are you just implying that the author is homophobic without reading the article?
The author is not claiming that the person's gayness caused the accident.
The author instead is claiming that because the engineer is a gay activist, that he is "untouchable" by the media.
From the article:
The “Amtrak needs more money” drums were banging from the earliest of wreck reports.
