Assholes from Boston are Irish and Italian. Roxbury, Matapan, Dorchester, weren't settled from those 2 countries, Even the Irish don't breed THAT fast.
To hell with PC, Those 3 towns, and Jamaica Plain used to be divided between Irish, Italian, and Jews, working class or better, where people didn't bother locking they houses. then in the 50's and 60's they made them start letting blacks move in until they drove out any decent citizens. Now they are all black shitholes of welfare, drugs and crime where even the cops only travel in groups.
And do gooder BS like bussing spread that disease through the whole city.
