Why the Internet is good and bad for politics

From Michael Gerson, Washington Post, "A Republican Party in Upheaval"

"The Internet allows people to find the like-minded, feed the intensity of their mutually held convictions and organize more swiftly and effectively. (It also allows people to filter out opposing views, anonymously attack their opponents and spread conspiracy theories.)"

That latter part is why so much pseudoscience can spread, assimilated, and regurgitated by people who have lost the inability to reason clearly and can only think in terms of their political ideology.
