The target is all symbols and reminders of history. Every Communist regime and every Moslem regime demands that the people believe that History started with themselves, that everything that went before is irrelevant or nonexistent. If no one knows history then they will believe anything they are told by “authorities.” They are not just targeting Democrat history but ALL history. That is why the subject is not taught in the schools any more which itself is why we cannot get the population back. The millennials to a large extant and the Zs almost entirely have no connection with reality and cause/effect as it played out in the past because they know nothing of the past. For them the Past started when they were born.
Eventually it will be the Constitution.
