because you can totally compare the glorifying monuments of the most evil men in history to a memorial for fallen soldiers
arguably said fallen soldiers fall into "evil" category as well, and vice versa for the monuments to the dictators.
times change and """monuments""" (since these arent /really/ monumental statues) fall and rise, this just is probably the modern day form of it. still illegal as forget though and they should be charged with vandalism at the very least
