As an American with deep Scottish roots I find all this talk both highly amusing and dreadfully scary. I'm all for another William Wallace scenario, as for too long there has been infighting, political bickering, cultural divide, and outright violence over these sentiments. Not just in Scottland too mind you, for we all still remember the days of the IRA; who ironically claim to still be functional. That being said your ancestors have shared the island for what.........since the neolithic age? You really are still ready to bicker, contest, and kill each other over your differences after this long.
It is not my place as an American citizens to really say what Europeans should do; due to the ideals my country was founded on. However I just find it outrageously silly your all still fighting over these distinct, and honestly minut, differences. Have 1,200 years of on/off conflict taught you nothing; or do you still hate each other because the lads of the north throw rocks, and those of the south drink tea? So to be fighting over something as stupid as oxygen(which BTW is that manufactured or just refering to the "air" in general??) is just...........outright bloody stupidity.
It reminds me of certain U.S Senators and House of Representative members who have, for such a long time, been trying to petition the goverment for seccession from the Union......again! The morons, probably drunk with power, don't like the Feds and really want to get away from them and all the horrendous policies they have been making in recent decades. On the following website, which the Obama Administration created for the sake of attempting to integrate the public in political matters, you will note that their are constant petitions for seccession of various states. (https://petitions.whitehouse.gov/
). This is honestly the work of sheer madmen, or those who have forgotten the bloody history of our past. Like these folks there are those in your country, and other European country, who cry for seccession with little reason or excuse for such actions. The consequences of these actions will be far more reaching than some short skirmishes and terrorist acts. It will spawn infighting for dozens, possible hundreds, of generations.
So in conclusion I think that if Scottland could rev up it's economy and go it solo all power to them. Just don't start the infithging the Irish did.....it will only spawn more unecessary sectarian violence. Beyond that the squabbles of politicians and their idiotic cronies is just them being bored and having nothing better to do. It's British humor as we say....it is it hilarious at times.
