I suppose it's "the border" --I have such a hard time processing those lies. I guess they must think that scary immigrants will get them?
Or maybe it's that idea they float about "Christians being persecuted" -- which is beyond wild in the US. This is a de facto 'Christian Nation' not only is it the majority religion, but most institutions and companies cater to the needs of Christians above all others.
But there really are people who feel... attacked.
