It's extremism to prefer the system that our founding fathers created and that we lived comfortably with for the first 125 years or so of our nation's existence?
I bet you don't think it's extremism to change the meaning of the 13th amendment to include the concept of gay marriage as a constitutional right. I doubt that you'd characterize it as extremism to get rid of the electoral college. I bet you think it's extreme to use the amendment process to change the constitution but it's not extreme to get a court to do it.
I'm in favor of repeal of the 17th amendment. The states should be more meaningful entities in our federal system.
