Parents and researchers who questioned FC's effectiveness and supported evaluating FC by objective methods have been accused of being "oppressors of the disabled," told they were narrow-minded, outmoded, evil, jealous they weren't the ones to discover FC, and, in some cases, accused of hate speech for advocating a more studied approach. Proponents claim that testing is demeaning to the disabled person, that the testing environment creates performance anxiety, or that those being facilitated may purposely produce nonsense, refuse to respond, or give wrong answers to counteract the negative attitudes of those who are skeptical of the technique.
