Sorry, but I believe there needs to be a social cost associated with groundless antiscientific FUD.  I don&#x27;t think it&#x27;s an exaggeration to equate fear of THz imaging physics with fear of vaccines, yet you cheerfully (and rightly) permit anti-antivax posts to descend to a deeper level of mockery and derision than I&#x27;ve employed here.<p>In general, I believe that advocacy of the precautionary principle belongs on other sites, and I&#x27;m very surprised that you and the rest of the YC staff don&#x27;t agree.
