I responded to the conclusion drawn that RobRoy's reply meant ipso facto that he "can't support" his allegation. That conclusion doesn't follow because RobRoy has been on the forum for 6.5 years. IOW, the length of time he has been on the forum is good reason to believe that he has in fact tired of fighting the same argument as he says. If he is tired of fighting the same argument, he should not bring the subject up! His answer is the typical dodge. I have asked several to support similar claims but none can. That leads to my logical conclusion that RR is just blowing smoke.
