From the article: “...both the flag and the seal depict a White hand grasping a Colonial sword over the head of a Native American person. Both emblems include the Latin motto “Ense petit placidam sub libertate quietem” which translates to “She seeks by the sword a quiet place under liberty.”
Being from Mass this doesnt surprise me. My guess is there are no indians actually actively looking to change the flag, just entitled white folks looking for some attention.
