Here are the 6 steps to destroying the Celtic Nations.
If you’re a Celt reading this then please don’t panic. You don’t have to do anything about it. It’s already happened.
(For Brittany, replace ‘English’ with ‘French’).
1) Move English people into Celtic nation(s).
2) Make the new immigrants protest to make their English language and culture equal.
3) Slowly turn a few locals’ minds against their own language and cultures.
4) Wait a while.
5) Pretend to care when Celtic pride dies and only an ‘insular and backwards’ minority remain to fight for it.
6) Complete assimilation and colonisation.
PS This should work on any nation smaller than yours. Give it a go.
