Los Angeles mayor shortens Mexico trip after clash "Some 25,000 people marched through Los Angeles on May 1 as part of nationwide protests intended to demonstrate the political might of Latinos and help win amnesty for illegal immigrants." Internal discohesion, in the wake of "barbarian" invasion. We do not use the adjective "barbarian" to imply any moral inferiority, and we do not wish to conjure up a polemic and politicised image of migration in general, which has been a constant in human history. We intend to use the whole term to describe the mass-movement of people from economically poorer regions to wealthier nations, which brings about a profound demagraphic/ethnic transformation in these countries and partly raises cocerns among their populations.
