Force the United Kingdom to rightfully give Northern Ireland their independence and right to be annexed by Ireland

The British have oppressed the Irish for more than 800 years. They won independence in 1921, but Northern Ireland still remains oppressed. When certain ethnic groups are persecuted in other countries, we act without second thought. When another country forces their way on to another ally, we act without a second thought. When freedom calls and another country rebels against an oppressor, we act without a second thought. This has been an issue since the 1920's. We have helped others in their fight for independence from England and we fought for our independence from them. Knowing our roots and the blatant violation of human rights against the Irish and Catholics in Northern Ireland, shouldn't we help them out!?!?!
