I am fairly confident that you have no idea what you are talking about.
None other than Adolf Hitler himself admired how "The American Union categorically refuses the immigration of physically unhealthy elements, and simply excludes the immigration of certain races..” [0].
If you are aware of how to immigration system specifically puts some people in a short line that takes 3 months to clear, and others of a specific national origin in a different line that takes decades to clear, with all other factors being exactly equal, and still believe that the system is working exactly as designed, we have a problem.
