Well first of all, Roosevelt was a Democrat, however radical.
And I have no quarrel with those who criticize the president. There are certainly legitimate criticisms--I have written my share of those to the White House and my congressperson and senators since Bush took office.
Then there are those who cannot criticize without demonizing and who cannot disagree without anger or even hating. I deplored those on the right who did that to Clinton. And I deplore those on the left who are doing that to Bush.
It is discouraging in the best of times. But in the time of war, when irrational fears and accusations and political trashing tend to embolden a vicious and irrational enemy, I think we have to be careful.
There were just as many peaceniks during WWII as there are now, but there was a strong reluctance by just about everybody to put our military at higher risk. The country was never more unified than it was during that time and it allowed us to have a decisive victory in spite of being so outmanned and outgunned at the beginning that we were laughable.
Sensible and rational people can make their opinions known while unifying behind and supporting our national leaders. That, for America, is the right course at this time.
