I have no dog in this fight and seriously would like to know who defines "extremist" and what is the definition? Clearly you have to know what the answer to those questions if you are researching "stuff"...otherwise how do you know what to research? Again, I truly am interested.
By the way, I completely admit and agree there are political extremism in the US...the only reason it is uncomfortable to me is because that is all people see on the slanted/biased/partisan MSM...when in reality, based on whatever definition your research is based on, extremism is a very small percentage of our population....however, you wouldn't know it if you watched the news. So again, I am very interested in your research to truly understand the data and how it's collected, measured, and reported so that people (aka ME!) can make ACCURATE opinions on the state of our society. Thanks
