It’s hard to argue that U. S. Citizens shouldn’t be leery of Mexican nationals. We can’t travel in Mexico in safety. Mexican nationals in the U. S. have made it unsafe here to an extent.
As for U. S. Citizens of Mexican ancestry, for the most part there is no need to be leery of them. Some, yes...
We have a few small towns surrounding us, 99% Hispanic, and yes it’s not safe to go there and just mill around. Same with the east side of our small citythat looks just like Mexico. And then there’s an area on the other side of our neighborhood , separated by a main road thank God, that is black that I won’t go driving through either.
And when you watch the news guess where all the shootings/killings are happening.
