I am NOT trying to speak on his behalf although it appears you are judging from your take on his conversation 18 months ago and no word on the matter since then. So until he steps in here and tells me I'm wrong and you're right I can assume anything I like.
If you wish for your opinion to have weight in the discussion IMO it is best to temper your passion to prevent it from saturating your opinions with arrogance.
Point to facts instead of creating them, stand in the middle and try to point out that anything other than fact-point is opinion and you will find folks will take what you say to heart more often than not.
Naturally you have every right to post in any manner you wish that does not break forum rules. You don't need my approval, recognition or permission.
