I can't speak to the gayness of Cape Town but will take your word for it. There is no record of Shrien ever visiting Cape Town, or indeed SA previously. You say "highly likely" as though its virtually a known fact that he visited, but its plain speculation just like the Dr Pox story. These sorts of tangential red herring stories just act as a distraction from the actual facts of the case.
Don't forget, first and foremost, he's been completely exonerated of any wrongdoing. Any talk of family honour, him being at risk of being disinherited, cultural pressures to marry etc are interesting topics in their own right, but have little relevance to the facts of the case. It just amounts to speculation as to a possible
motive. But what's the point discussing possible motive when there isn't any evidence whatsoever of wrongdoing? The judge quite rightly decided that that little sideshow was of no value to the court. She was looking for evidence of guilt but all she found was fabricated evidence, contradictions, and lies specifically designed to incriminate the accused - it's all there in the judgement. http://www.saflii.org/za/cases/ZAWCHC/2014/188.html
