A statement by them a few days ago: "The most compassionate approach that balances the risks and benefits of reaching herd immunity is to allow those who are at minimal risk of death to live their lives normally to build up immunity to the virus through natural infection, while better protecting those who are at highest risk"
There's a very obvious problem here. Those at high risk have to intermingle with everyone else, and most at high risk don't know that they are.
You don't just 'gain herd immunity'. You get the virus, be contagious, give it to anyone else you come in contact with, and they go out and do the same. People can't afford to quarantine and refuse it. People will not wear a mask, they don't care. Americans whom won't die from the virus will not take it seriously.
In reality barrington is advocating that people die. Which if they're doctors they've violated their do no harm promise - not that it ever meant anything.
As far as I can tell barrington has no leg to stand on. It doesn't matter if they're supposed 'experts', if they're right then they can prove it.
