It wasn't really an invasion as in a war but a colonisation this was occurring all over Europe as any history book will tell you were you ever to read one. Scotland has invaded England France has invaded England
The colonisation of Ireland was in the 16th century brexit was not a part of that. But again it is in your world. There is probably no where else in the world that's still fighting battles of 400 years ago there was a civil war in England then in fact three civil wars never in my life have a met anyone who today is remotely bothered most probably could not even state those facts.
The fact there are still people like you is immensely depressing and it makes me think there is no hope for Ulster the bitterness and hatred are always under the surface and for what reason ? I don't believe it's anything to do with the 1600,s more likely turf wars over drugs / other crime and frankly very small minded communities where this is allowed to foster.
So your argument is that because something happened long ago it doesn't really count. Even if the consequences are still felt today. Also a brexiteer accusing others of being small minded is actually very funny.
Add that to the fact that you are literally huffing like a child because Ireland won't dance to Britain's tune and it still doesn't mean that you can post utter drivel.
Even at this late date we are still waiting for the brexiteers alternative plan that will break the deadlock and lead Britain into a period of wealth and prosperity.
What better time to launch this plan than during the Tory party conference, but unbelievably we are still waiting.
Surely they have a plan?
