PFR,

"Yes, I do respond assertively to opinions I disagree with,
and will continue doing so..
All opinions are not equal, or to be respected...!!!"

I would agree with this. I hope you allow others to be the same way.


IMO, I do not see that "we reached a point where Jim despairs of ever having any serious debate on this subject"

I see that JC has not been able to persuade some of us to agree with his opinions, and he has failed to even consider others. If we ask for supporting information, he takes it as an attack rather than chance to enlighten others- and he refuses to "discuss" anything- his opinion is the only one he admits might be valid. I see no effort on his part to "debate", just lecture and demand other's acceptance of his opinions as proven fact.
