Scotland, Ireland and Civil War

I think some SNP politicians are losing their marbles over independence and the following quote from Joanna Cherry MP is a case in point.

“One hundred years ago Irish independence came about not as a result of a referendum but as a result of a treaty negotiated between Irish parliamentarians and the British Government after nationalist MPs had won the majority of Irish seats in the 1918 General Election and withdrawn to form a provisional government in Dublin.

"While no-one wants to replicate the violence that preceded those negotiations the Treaty is in legal and constitutional terms a clear precedent which shows that a constituent part of the UK can leave and become independent by a process of negotiation after a majority of pro-independence MPs' win an election in that constituent part."

Independence in Ireland was achieved after a civil war and it seems to me the underlying causes which led to an armed struggle don't exist in Scotland - even remotely.

I can't understand why a member of parliament uses such wild rhetoric, but read Mark Smith's opinion piece in The Herald and decide for yourself.
