Ethnically Irish people in Northern Ireland started a thirty year civil war that killed 3,000 people to stop a deal, called the Sunningdale Agreement, that gave them legal equal rights and the right to self-determination.
They then blew up a shopping centre to protest an almost identical deal in 1998. Thankfully the war did not restart.
And I'll just put that out,every nation that ever persecuted Jews (their modern equivalents). Which is..
Iraq Egypt Saudi Arabia Yemen Oman Iran Turkey France Italy Spain Portugal UK Denmark Germany Russia Ukraine Latvia Lithuania Poland Estonia Austria Hungary Romania Serbia Moldova Belgium Netherlands Ireland Israel Syria Lebanon I could go on forever. Yes, Israel has had problems with Muslims, but such acts are more politically inclined, and not at all Christians.
