That is why I normally ask where people have gotten their information, to determine how solid statements are grounded to something meaningful.I have no problems with opinions, I just like to know this so I have some way to guage the reliability of what is being expressed.

What constitutes an expert is another good question. We are all familar with the court system and the process courts go through to recognize someone as an "expert" witness. Then we see a bunch of experts on either sides giving completely different expert testimony.

Just because someone is consudered an expert does not exclude them from error, in judgement, opinion or otherwise. However, it does increase the liklihood that they have tied their statements and opnions to something well grounded.
