Appeasement never works, ever.
No matter what we do, the race baiting poverty pimps are going to castigate us. Period. They won't be emboldened if we dump Lott. They won't be satiated if we do. Appeasement is giving something an oppressor wants to them hoping to get them to ease up. They won't ease up, and they don't really want Lott gone.
The people we would be making a change for are ourselves for our own moral integrity and political benefit when aiming at the voters we hope to sway. We would not be making a change hoping that the baiters would stop. They won't.
In other words, other than for our own integrity, the people we are aiming for are not needing appeasement. The undecided voters are not the ones clamoring. But they are ones who will be listening in a few years to all the ads, and they are the ones who will be watching what we say and do.
