But the administration isn't directly affecting Americans -it's affecting some people who had legal residency (green cards) in the US and will for the time being affect potential visitors from select countries for 30 to 90 days.

When he ran, he ran on a platform to do good by America and Americans --none of the world shaping vision other presidents had (which then led them to foreign interventions which then lead to people calling America imperialistic and other tangling messes). So, it should be of little surprise he does not care very much about non-Americans (I think he takes that belief literally) and will try to deliver on it.

When the ACLU gets involved, I don't even see the "American" part of the civil liberties in there. I mean, good on them for caring, but at the moment it's doing work on behalf of foreign nationals, rather than Americans, directly.

While this may affect some friendships and relationships for Americans the impact is indirect.

Where is this policy affecting the civil liberties of American citizens? Obviously it's affecting some foreign nationals negatively.
