Consider these Memorial Day weekend headlines:
Vandals Deface Vietnam War Memorial
Purple Heart plant bed vandalized days before Memorial Day
Vandals strike Anniston veteran's memorial for second time
Is it just coincidence that we've seen an increase in these types of acts since the feeding frenzy on Confederate flags and Confederate monuments? No, I don't believe it is. As I've said over and over, Confederate iconography is the low-hanging fruit. It's the whole of American history that is under attack and it's politically and ideologically motivated. America's history and founding must be evilized for the moral reformers to prevail. Activists and certain historians have created and encouraged an environment where everything representing America's "evil past" must be destroyed. Don't forget that. It explains much of what you're seeing, both in the news and coming from a number of academic and professional historians.
