And no, Kirk is not some "insane radical".
But ... but ... he's a Republican. To many of the commenters here anyone to the right of Elizabeth Warren is an "insane radical". Because justice and equality and puppies.
Yes, Kirk is a member of an insane radical right-wing political party. Which explains his insane commentary on Greenland, his radical support for racial profiling, etc.
Anyone
sane who tries to run for office as a Republican will be immediately targeted for elimination by the deranged base of that party.
