I understand Ageod wanting to avoid political flame wars, but its hard to intelligently discuss the ACW without touching on the politics OF THE TIME. For instance Lincoln's mid war re-election was a critical part of the Civil War, and of course like all civil wars its causes were basiclly political.
I propse that if people stick to the period and are civil and considerate to other posters (aqs I've found the fast majority of posters here to be) that a absolute ban on all politics isn't nessecary or desirable.
