Because the exasperated tone of the article is too reminiscent of the cock-sure fellows who proclaim on the "Predestination" threads over in the Religion Forum.
Whoever wrote this, has an emotional stake in the outcome. I don't trust it.
However, the exasperation may come from seeing supposed scientists who also apparently have an emotional stake in their own pet theory... and who refuse to see the writing on the wall that their theory does not meet the observed facts... and who continually marginalize a theory that DOES meet the observed facts, time and time again. That can be very frustrating.
