Senate Majority Leader Harry Reid is under fire from Republicans after comparing opponents of health care reform to those who resisted the abolition of slavery and women's suffrage. ("You think you've heard these same excuses before, you're right. In this country there were those who dug in their heels and said: Slow down, it's too early, let's wait, things aren't bad enough about slavery," Reid said.)
On a scale of 0 to 10, how controversial/offensive is Reid's comparison? Is it?
