In Europe, after a few quiet years violence is now on the rise again.<p>And once again it is between etnical groups. (The previous that I can think of where mostly Northern Ireland and Northern Spain with a few lone wolves in between.)<p>Not arguing here that immigration shouldn&#x27;t be simplified but be ware that it isn&#x27;t just rainbows and unicorns.<p>&gt;  foreign nationals are denied basic rights that US citizens take for granted<p>I&#x27;d say at least modern US is skeptical to everyone, regardless of race, religion, color, ethnicity etc - don&#x27;t we regularly complain here about how TSA even stops US citizens with US passports at the US Border? : )
