It's not Lefties or BLM or upset victims of abuse.
From the 'idol' painted on the statue of Mary, one can deduce that it is simply Iconoclasts. Most likely Protestant (of which I am one...of the various varieties) in origin who believe that icons and statues like this are blasphemy. To depict the holy and sacred (Jesus) in mere stone or to make that which is merely human (Mary) into a holy/sacred figure through making of statues (made by the hands of men) is idolatry to them.
Someone has just gone a little too far and taken a spray can and bat to these. Hopefully, they catch those responsible soon and give them a hefty fine for damaging property.
