I don't like the term because it implicitly attempts to devalue the results of Scottish elections. I do agree there are certainly entrenched views on both sides but "too" entrenched? Not for me. If you believe that the Holyrood system produces at least a relatively proportional result, there is an undeniable majority for Yes in parliament now which would show that there is movement.
100% this. It suits a certain element of unionism to pick and choose themes and policies from NI to emphasise the existential threat they feel they are facing, undermine the Yes cause and portray us as extremists. But curiously they're less keen on the Stormont definition of a generation or the right to hold a border poll should they elect a government to do so.
