Yes, a point of view without an ethical backbone, at least in the context of American society. I suppose they could be a Chinese or Russian national considering it ethical to harm the United States, but I don't see a point of drawing that distinction.
Being blanket against CBP is a position without an ethical backbone. It’s just a childish burying head in the sand. Every semi stable country enforces its immigration laws and checks passports of visitors. Claiming the US doing so is somehow unethical is completely misaligned with a sustainable welfare and government services system.
