You're both wrong.
With non-citizens already in our midst responsible for crime waves, some domestic surveillance may be a regrettable but necessary but is still A Bad Idea.
And likewise, open unchecked borders are a mistake, and the treatment of children is way overblown and misrepresented. Obama never performed DNA testing to find the obvious child buyers.
Here is context of Trump's tweet about the Fabulous Four,
1. "Why don’t they go back"
2. "and help fix the totally broken and crime infested places from which they came"
3. "Then come back and show us how it is done. These places need your help badly..."
How many of your chosen news sources and celebs are only quoting #1? How many have consistently failed to quote #1,2,3? Is it 'racist' to tell people to go, then come back and show us how it's done?
THIS is why open unchecked borders is a bad idea for the most desirable developed countries,
