Simple. Statues are relics of the past, predominantly representing the dead. When you engage in a battle, would it not be an easier battle if your opponent was dead? And as most are indifferent to such statues, the attackers can feel a sense of significance and purpose when an inanimate object has been vanquished.
Who has the time for this kind of BS...unless they are being paid for such activities...
All of this is for one purpose. The left is trying to intimidate the country. If they do not get their leaders of choice, there will be no peace. Are you intimidated? Are you frightened by their assault on inanimate objects, their signs, their masks? Intimidation tactics call for those resolute to take a stand.
