They were never in power in the first place, hence the main difference.
Look at the ANC in S. Africa. 30 years of power, Mugabe in Rhodesia, 40 years of power, happens all over the world when these populist types get in.
The SNP have already outlawed naughty words in songs, they've already tried to steamroll the Orwellian 'named person' thing through, they are dangerous and decent people need to open their eyes and see what type of future they are being duped into.
SNP are green - want to base economy on oil.
SNP are socialist - plan to lower Corp tax for big business to relocate in Scotland
SNP are progressive - ban singing songs with naught words.
SNP will creat jobs - SNP centralised the police (despite them being told that they would no longer be VAT exempt) and forced early retirement on hundreds of police officers.
They are VILE and any person who votes for them without analysing their record in Government is a pink sock.
