I thought my position was quite concise. Let me try to rephrase... Anyone can make up rubbish: an unworkable hypothesis. But until you can come up with a workable model, you can't claim to have bettered anything. So I can't see what there is to defend here.
Your aeroplanes suck because my aeroplane doesn't crash. < problem with this hypothesis: non substantiated claim.
