It very quickly escalates to discrimination against Chinese people in the US, as evidenced by the highly upvoted comment I originally responded to. I'm sorry if I get my knickers twisted about people proposing an entire race of people pose a national security threat, but this sort of xenophobia has rarely gone well in history.

Chinese and Russians living outside of China and Russia will not be affected by the ban.

You keep calling it xenophobia even after you've been proven wrong when you claimed this is targetted at green-card holders. You are absolutely disengenuous and have no intention at good-faith discussion.

I then suggest you edit out your erroneous personal attacks.
