Hard to fear monger when the 'others' are coming here by airline. Much easier to fear monger and pick on the poor 'brown' people who can't afford to fly and are looking for asylum escaping the dangers in their countries. Unless you have 100% Native American blood then your ancestors came from somewhere else also. Many of them seeking asylum from dangerous countries as well.
We've seen this playbook before. Many ethnicities like the Chinese, Italians and Irish along with other ethnicities were all subjected to similar ugly racist / bigoted lies. There will come a day when you hear the name Sanchez and Hernandez and not immediately think of their Hispanic ethnicity. Just like when you hear the name Pelosi and Giuliani and don't think of their Italian heritage.
This president and his surrogates at Faux News with their racist fear mongering has encouraged the racists and bigots to come out of the closet. Like I said we've seen this playbook before. No less ugly, but instead of using dog whistles, they now use a bull horn.
