And Me too?
Some Forum Members, doesn't include me, that wish in a general sense to send "them" back just because - that is prejudicial and not my style!
As it relates to you, personally, I have responded to comments of yours but never to suggest you go back to where you come from - out of casual interest, is that England or USA?
I do think that the book you highlight above suggests an exaggeration of what personal (mis)apprehensions you may have especially as that relates to internal politics in a country and not the opinions of a few bigoted people on social platforms.
