Whats the most intellectually stifling movement in America..?
The deliberate dumbing down of America is what is intellectually stifling it. Politically correct “equality” means that the lowest scoring underperformer is now the bench mark for excellence. Point at any group or institution you care to choose and say they are to blame, if you want. It’s easy to look for someone else to blame, rather than admit that it is well meaning but badly administered social policy that was designed to give everyone a fair deal that is to blame. What has stifled America is America.
