America's intellectual community has never been very bright. Or honest. They're all sheep, following whatever the intellectual fashion of the decade happens to be. Demanding that everyone follow their dicta in lockstep. Everyone has to be open-minded and tolerant of the things they believe, but God forbid they should ever concede, even for a moment, that someone who disagrees with them might have some fingerhold of truth.
The quote criticizes the American intellectual community, suggesting that it lacks both intelligence and honesty. It portrays them as conformists who blindly adhere to prevailing intellectual trends without questioning or engaging with differing views. Instead of fostering diverse perspectives, they demand that everyone aligns with their beliefs, all while promoting an image of open-mindedness.
This criticism highlights the irony within the community, pointing out that while they preach tolerance, they are often unwilling to acknowledge the possibility that opposing opinions might hold some valid points. The author, Orson Scott Card, emphasizes the importance of genuine discourse over mindless conformity in intellectual discussions.
