Speaking of old tricks
Standard attack politics, laserbrains:
1) Mistate victim's statment (bring up chlorine)
2) Couple demand for information with insult
If vicitm provides information, insult stands.
If victim responds to insult, cry foul - plead for "fairness".
3) Avoid reality that conflicts with attack:
Once again, shuttle grounding has been followed by a reduction in the rate of ozone depletion"
The same thing has occured following the Columbia grounding as occured following the Challenger grounding.
Their theories (not my theoris) have been predictive, and have causal mechanisms described.
If you have another explanation for the observed phenomenon, I'd sure like to hear it.
Oh well.
