Confronting 40-20's typical extreme posts....in this case belittling 5th graders is hardly "uncivil."  Pointing out that climate-change deniers are also denying reams of scientific evidence and the views of 99+% of climatalogists is hardly uncivil.  I am addressing opinions and actions....especially the actions of belittling and dismissing the demonstrations of concerned young people who are expressing their support of a issue.  

I do, in fact, classify climate-change deniers along with flat-earthers.  The only difference is today climate change is far more menacing.
