Did Irish immigrants bring disease to America , Yes , they arrived under nourished and lived in filthy shanty town that did indeed spread disease . Many of the USA ' s violent black slums started as Irish shanty towns , North saint louis is an example . Were Irish Americans criminals , yes , they started organized crime in America . Were Irish Americans drunks , yes , there is a genetic component to alcoholism . Did Irish Americans take jobs from Americans , yes , they even made it uneconomical to use slaves in certain dangerous trades . And perhaps worst of all Irish Americans were and are huge supporters of the Democrat party . So lighten up when people speak the truth about Mexican immigration , it is a nasty business . And the bottom line is white American racists treat poor mexicans better than the mexicans do . Just like Irish Americans were treated better by American racist than by their Irish and British rulersSnapshots This Post run 1 , maxh 1536 w 1536 s 78 a 5 f 4 b 99 d 8544 a 8 c 5 c 9 eea 837 b 33 a 3 a , I am a bot . relsbot relsbotsubmit ? selftexttrue
