Well, it's true, land was taken from the indigenous folks. Not like the early migrants from Europe bought the land from the native.
That's arguable.
he population density of North America was much lower in the 17th century. Lots of the first colonies were established on land no one was activly using, and 17th Century Native American views on land ownership were very different from what they are now.
It should also be noted that many times over the course of the establishment of the colonies, the Brits attempted to buy the land they were settling from the locals as they settled. Translation issues and differeing views on "ownership" hampered this, but clear effort was made.
Certainly, later in the expansion of the US we just took land as we found it.
We also fought and won wars to conquer land (not just with Native Americans). In the historical context it's lying to call conquered land wo in a war "stolen". It's not ideal for the losers, but it is the way the world works, and by world I mean the whole world animals kingdom included. You only keep territory you can hold against conquest.
So while the "Stolen" soundbite is catchy, it's only partially true, and mostly historical revisionism and wishful thinking.
Also Ben and Jerry's is overpriced mediocore ice cream.
