Flag of Connolly

Strange logic on display. James Connolly was cause X, he died for flag representing cause Y, therefore flag represents cause X.

The cause of Ireland is not a socialist cause. The flag of Ireland is not a socialist flag. A socialist dying for Ireland does not change the cause of Ireland to one of socialism.

Apart from that, describing James Connolly, a returned member of Irish diaspora, as an immigrant is absurd. They will attack ethnic nationalism without knowing the first thing about it.
