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.

The problem is not the roles, but how those roles are carried out and the complete lack of accountability. It's difficult for citizens to believe that government agencies are noble endeavors when we see ever-creeping anti-Constitutional scope, and rampant unpunished criminality among their members. It would be fantastic if this weren't the case, of course. Unfortunately the only check mechanic we the People seem to have is to consider them hostile entities best avoided until they're drastically reformed.
