No problem. I view the primary point of these boards as reasoned give and take. The whole point is to shoot reasoned holes in others theses - and have holes shot in yours. I don't 'enjoy' having such holes who in my theses, but it is invaluable.
Sadly it seems to be disappearing somewhat - e.g. Among the biotech cognoscenti on twitter there is rarely much obvious and direct reasoned disagreement.
