The strongest case on each side of every major political topic, stated as its own advocates would state it. Each topic runs as a pair: the progressive case on the left, the conservative case on the right, each a single argument that answers the other side's best points without ever pointing at them. Beneath each column, an open floor: any reader can submit a better version of that case, capped at the length of the longer column so no one wins by volume.
On method. Each case is built from what that side's own most prominent advocates actually argue, not from how opponents characterise them. Where a movement is split, the split is reported rather than smoothed over. Word counts are tracked and kept within a few percent of each other, because length is itself a form of advantage.
How reader arguments are handled. Every submission is read by a person before anyone else sees it. Nothing publishes automatically, and there is no voting: what appears under a topic appears because it was judged to make that side's case stronger, not because it won a popularity contest. Expect roughly a week between sending an argument and seeing it.
The standard is simple. An argument earns its place if the side it argues for would be glad to have it made this way, and the other side would have trouble answering it. Restating the column that is already there does not clear the bar; neither does insulting the opposition, however cleverly. Both columns stay capped at the same number of reader arguments, so one side can never crowd out the other no matter how lopsided the site's population becomes.
One argument per side. A submission makes a side's case from the ground up; there is no separate reply format, and no threads. An argument you disagree with is answered by making your own side's case better, which is the discipline the editorial columns hold themselves to as well: each absorbs what the other side gets right and answers it in its own voice, without ever addressing it directly.
Length is capped at the length of the longer column on that topic, because no one should win by volume.
Who carries each case. These are the writers and broadcasters whose actual arguments the two columns are built from.
