Because you’re not going to like the answer to where the line is.
The answer is the line has been crossed for decades. It was crossed when we started this nation recognizing slavery. It was continued when we kept breaking promise after promise to native Americans. It continued being crossed when we threw thousands of Asians, especially Japanese into camps.
It’s been getting crossed when we’ve sat by and justified police brutality against minorities.
It’s been getting crossed when we killed hundreds of thousands of innocent people.
It’s been getting crossed when we’ve been supplying weapons to the global south knowing full well how that’s going to be used.
So, realistically speaking, that line doesn’t exist anymore. And the American middle class who never backed the American poverty class when they protested this, are going to find themselves alone and without support.
The whole premise of the question “when will the line be crossed” reeks of privilege and shows a fundamental lack of understanding of where we are today.
Does that help clear things up?
