When was the last time you visited the USA?
To suggest that as much as 4% of the American population is "racist facists" demonstrates, I think, a rather profound misperception of Americans.
And to suggest that 4% of Freepers are "racists facists" suggests to me that you might be spending to much time over at DU.
What planet are you on? Perhaps not understanding what "reading between the lines" means when it comes to some of the posts at FR and as far as the American people are concerned, my (always) conservative guess is somewhere between 4% and 6% - which is probably low. There are more than that number of Southerners alive who adamantly supported segregation and Jim Crow laws. If you want to count a few, start with the Senator from WV.
By the way, I am in the US 4-6 times a year and mostly on the liberal East Coast and rural PA. The percentages hold true - perhaps you don't get out much.
