Although it dissimulates an effort to isolate and neutralize subversive historical information that challenges its norms, the spectacle's willful ahistoricity by no means represents a politically safe procedure since the peddled historical anecdotes that are substituted for real critical history may actually trigger some levels of self-awareness among discerning consumers, making it possible for the opponents of the system to acquire a means to replace the official idols within alternative hermeneutic contexts, thus undermining their integrative aims.

虽然dissimulates为了孤立和压制颠覆历史资料，其规范的挑战，壮观的任性ahistoricity绝不是一个政治上的安全程序，因为兜售的历史掌故是取代真正的关键的历史可能会引发一些层次的自我宣传消费者之间的辨识，使对手的系统获取的一种手段，以取代官方的偶像内替代诠释背景，从而破坏他们的综合目标。
