The link wasn't working for me so I had to read around to get the gist of what was going on.
His rather wonky interpretation of Darwin doesn't endear me much to his scholarly credentials.
If he can't get his head around On The Origin Of Species By Means Of Natural Selection Or The Preservation Of Favoured Races In The Struggle For Life, I would take any conclusions he takes from a more historically coiled and linguistically challenging text like any version of the Christian Bible with a pinch of salt.
If those conclusions lead him to show physical signs of revulsion at the suggestion he may have a homosexual friend then I doubt if he would find approval from his saviour.
It is definitely not the way of the Master.
