&gt; When hundreds of millions of people keep buying things you believe are awful, perhaps it&#x27;s time to ask how broadly shared your views are.<p>It&#x27;s irrelevant how many people believe in something if they&#x27;re wrong. A billion people believe the Earth is 60,000 years old and was created in a week by an all-powerful bearded deity. That doesn&#x27;t make it true and doesn&#x27;t mean we should throw our hands up and reinforce those beliefs instead of improving education and displacing them.
