&gt; It&#x27;s quite normal to deny something the entire scientific community is saying.<p>By other scientists when doing science sure, that&#x27;s cool; by the ignorant public when working on policy, that&#x27;s just ignorance.<p>&gt; Most of our current scientific knowledge was originally someone disagreeing with the majority.<p>No, if you are not a scientist in the field, your disagreements are just ignorance.  Science can and should be challenged by those actually doing the science, not arguments from ignorance from the general public.
