I get the sentiment, and am also so, so tired of this. But. It's an election year and Biden is currently president. In other words, these freaks will absolutely shut down the government, actively harm the economy, and reduce our national security because they can then blame democrats and it will help elect Trump. Please vote, donate, and volunteer accordingly....
They would never. They can threaten all they want but what they are really risking is the dollar as the dominant currency. If it becomes commonplace or even somewhat likely that a shutdown can happen, the rest of the world sees that as instability. These fools don't know what levers they are messing with and the second someone actually pulls it they will shit their pants crying because they made a booboo.
