Tbf I do think (both north and south) while it should be taken seriously, it's a bad move to believe that the sentiment is overwhelming. It's that which leads to eg Keir Starmer thinking you need to pander to those clowns. You don't! And you shouldn't!
For real it is absolutely brutal. Anyone I knew who was pro-indy in 2014 was so because they believed things could be better. The entire thing of BT was things are as good as they can be. The "u kan't eat a flag' shit was pure projection
