I do not appreciate your attitude in refering to to you and us and you presumably being from ethnic Irish origin. In that case one could say no one asked you and your aggressive Buggie to come here. You could of course return to the woes of Southern Ireland.
As for N Ireland the so called invaders are the decendents of mainly Scottish emigrants ( not English ) . Authorised by King James the 6th.
I am really puzzled by your mention of Britoil.
Regarding Highland Clearances they were mainly the responsibility of Scottish Landlords. Also I would have thought most of their decendents in Canada , USA and Australia are happier where they are now.
