Wrong side of history

I saw on TPM where Sens. Thune, Hatch, and Coburn pretended to be offended by Reid comparing Republican obstructionism on health care to those who blocked an end to slavery, Jim Crow, etc. I wrote the following to each of them:

As Rep. Grayson put it, Mr. xxxx, we the American people do not care about your FEELINGS. You are, indeed, obstructing progress in just the same way as rightists of old attempted to block the end of slavery, the end of Jim Crow, and any number of other progressive changes. You are very much on the wrong side of history, and if the criticism stings, it is because it is TRUE.
