I’ve never had it said to me, and I’ve never said it to someone else.
Similar but not the same, there was a time when my SIL had only negative things to say about America and seemed to long for life back in Mexico. It became annoying. I actually have no problem with people missing things in their country, I miss things about almost every city I’ve lived in, it was more that she had not one good thing to say about America at the time. She was just going through a bad time.
At the time when she complained constantly, when we were together with groups of people, (friends and relatives) they would say to me behind her back, “wow, what’s with her, why doesn’t she move back if she thinks it’s so much better.” Again, I never felt they were being bigoted. If she had been talking about Phoenix, AZ they would have said why doesn’t she go back there.
I don’t hear people around me saying to people to go back where they came from, although we did have that one guy yell out “White Power” recently, which Trump saw fit to tweet so we did have that. Ugh.
These people screaming at immigrants or some of these people aren’t even immigrants, they are born and raised in America, the people screaming are just total idiots! I actually am very pro-assimilation, and the way to expedite assimilation is to be welcoming, not the opposite. These hateful people would create their own self fulfilling prophecy, except thankfully most Americans are not hateful.
