<<I see the incentive of some to generate such a thread. This is a collection of intelligent, well informed, folks. So the temptation to engage them in strong. But I've seen such - be it politics or stock trading - ruin other other boards.>>

Agreed. I have merged all of the recent Biden posts with a new board titled “US Policy”. The full Biden thread is now here - please continue adding to the thread:
Cardude replies on Biden Budget

If new posts relates to US politics, please post it on the US Policy board rather than the Berkshire Hathaway board. If you wish it to be with the audience here at Berkshire, it is no problem at all and just add a post here and copy-paste the URL to your post on the US Policy board with “OT:” in the subject.

I have also moved all posts on the Atheist Shrewds board to US Policy, as at least 95% of the posts there were actually of that subject - US politics. 

The new Atheist Shrewds board will hereafter be a meeting place to discuss philosophy and life, as you might in a community hall, but not wanting to do so at religious church. The US Policy related posts will be split off from it to the separate US Policy board.

I have also created a Political Asylum board to discuss politics where there would ordinarily be fear of censorship elsewhere, but protection from that here, giving it a completely different character to the US Policy board but also covering political discussions.
