Back in the 90's when the Democrats were in control of the Federal Government, a guy tried to crash his plane into the White House. He hit a tree and died on the White House lawn. On another occasion, a guy stuck a gun through the fence at the White House and fired off several rounds before being tackled by civilians. When Newt engineered his "American Revolution" with his "Contract On America" regaining control of the House, fanatical wingnuts seemed to calm down.
Now, after Republican rule over two wars and doubling the size of the Federal Government and debt, Katrina, Schiavo, and just all around dickeadedry, America has turned its back on the fanatical 20 percent that remains of the Republican Party. The anger has risen to a dangerous level and is manifesting itself in recent killings.
Ann Coulter once said "Not all Muslims are terrorists, but all terrorists are Muslim."
I think it is fair to say that not all Republicans are racist, but all racists are Republicans.
