If anything, this conjures the plight many American Indians suffered at the hands of the US government.
So, are some people just squealing because they don’t like the message? Or is there some irrational meaning some are deriving from this billboard?
Personally, I think this is typical leftist faux outrage. Although I don’t identify as a native American, it is part of my heritage. I’m not offended. And, I view this as a perfect example as to why there is a 2nd amendment.

I suppose one can be offended by historic reality.
Did Ward Churchill complain again? 😉
That billboard reminds me of the Trail of Tears. Hmm. Leftists don’t grok history.
It uses their likeness without their permission.
Not faux outrage from the left, real outage. Because their chronic immaturity is real.
