Agree, the timing for Scotland leaving now is terrible. Yet I also feel a tug thinking how there never has been a good time for England to lose any of her colonies, including India, South Africa, Hong Kong, the Falklands, her 13 colonies right here, etc.
Scotland is not and has never been a colony of England.
Just FYI HK wants to rejoin the UK (they didn’t become independent, they became a colony of China instead)
