I asked and someone answered - why toilet paper hysteria?

Every so often, I think I'm surrounded by complete morons and the only one with half a brain is me. 

One person's collection

In Australia a mass stampede of irrational dullards and others in the lowest percentiles of their classes has been created by the COVID-19 virus. It's NOT a gastrointestinal virus, but never mind, hundreds, possibly thousands of the aforementioned have rushed off to overstock on toilet paper.

It seems that a couple of people were seen by the media buying toilet paper and mentioned they wanted to be prepared for confinement during the coronavirus outbreak. The news hit the TV and ignited the stampede.

With that and other stupid things that are happening eg, the Professor who said we should all kill ourselves so the world would be a better place (perhaps she should have led by example), and the imams in Indonesia who said that the coronavirus was allah's revenge for people eating pork, although there are probably hundreds of inflicted who haven't eaten pork, I wanted to know how mass hysteria occurs.

My question was answered by someone smarter than me:

Now, I'm worried about running out of toilet paper, as to buy it might mean people thinking I'm one of the intellectually vacant buying it to prepare for a virus.
