My comment was about how people assign themselves a self-importance that is meaningless in the the grand scheme of things. Not sure why you are talking about race or religion.
It will take me close to 24 hours to reach American soil. Depending on my luck, I might either:
a) pass without issue, or
b) hand over my phone and passwords and/or complete CS puzzles (which may also include period of detainment)
They can turn me back for any reasons and I would have lost thousands of dollars: if my answers were unsatisfactory, if there were some prejudice against my look, or even if the officer(s) were having a bad day.
