Talk about a lack of self-awareness.
The knee-jerk over-reaction was all you due to your misunderstanding. Clearly, I didn't misunderstand you and my response was on-point. You need a better criticism to justify this response.
Sorry, bud, but don't dish it if you can't take it.
It's been explained. People are preparing to stay home and isolate themselves. Some people don't like/drink tap water. Their preference for bottled water has nothing to do with the virus. Some people also don't like running out of toilet paper and exposing themselves to potentially infected people to get more when they could have just bought more to begin with. If you'd rather wash fecal rags then why do you buy toilet paper normally?
You have your answer.
Those people welded into their apartments probably wish they could've had one more supply run first even though they are getting some supplies (food, medicine).
We'll just revert to using our left hand. We're still civilized. Honest!
While the carts and pallets we see people buying are excessive,l and some probably are simple stupidity, there are many other possible explanations. Maybe the person runs an orphanage or a boarding school!

They could be buying for other households... friends and family. Heck, they could be buying to scalp.
He called you that because your entire post was a straw man ridicule of another forum member which is decidedly against the rules now. Both of you were out of line but his intent seemed more to tell you that so that you would self-reflect. If so... *WOOSH* Regardless, calling someone a "moran" because they called you a dick just seems petty and doesn't really save any face.
...and now you are attacking my comprehension about how preparing for the next situation is or isn't political. It's not "political" as we define it just because it requires political action. If all sides agree it needs to be done then it isn't a political issue and, thus, we describe it as "not political." Pretty simple.
No one said that increased self-sufficiency and domestic manufacturing capacity in the future can help with this novel outbreak. That part of the discussion is about how supply issues with this outbreak can help us improve for future novel outbreaks. Discussing this is extremely relevant and shouldn't upset anyone.
