I got a good story for you.
Me and some friends were at a bar and this came up, and a mexican fellow asked us why we don't want mexican illegals here, one of my friends said "the same reason you don't want illegals from central americans in your country".
This mexican guy went off on a long blubbering incoherent racist speech about the countries in central america, and why they were all bad.....and then kept rambling on about how horrible the people were from each south american country (going one by one), until the staff threw him out.
The kicker, as the bouncer was dragging him out (with this guy still screaming racist remarks about people from columbia) someone yelled out "don't just drag him out the door, take him back across the border".
It was a very surreal moment (funny, then disturbing). He soundled like a cracked out la raza klansman.
