First of all, how can you justify his comment about common sense when that certainly was directed to me and can easily be construed as offensive. What is inappropriate is his reference to "common sense" being the only way to qualify the differentiating factors in hybridization and how it relates to w/c individuals. If you feel that Eddies comment was a reasonable contribution to a educated question directed to clarify a perplexing issue I have to disagree. Confrontational? No. Just challenging Eddies response that to me, is not only inappropriate but its inadequate as it doesn't EXPLAIN any part of the original question. None of us know it all Steve that is why we ask questions. "Just continue to read" was preceded by my comment and my interpretation of his ( Eddies) less than helpful , poor , explanation of the hybridization of w/c's. How can the differentiating factors and any signs and or physical attributes of hybrids just be "common sense"? Come on, and your validating what he said?
