Voters of the SNP tend to do so wanting a better future for their country.( I’ve no idea about PC) The nationalism on display in England, and the Brexit type nationalism, seems to be harking back to some mythical golden age of Britain. Similar to the Maga pish across the pond. It’s seems to be violent too, why that is I don’t know.Maybe we could learn something from Scotland and Wales? They have more mainstream political outlets for their 'flag shaggers' in the SNP and plaid cymru. This probably serves to keep the idiots off the streets, whereas we (in England) tend to recoil from overt nationalism/extremism although the last decade has seen an uptick in conservative and labour politicians appearing with the union flag as a backdrop. Maybe if Reform can become our version of plaid/SNP then it will diffuse the perception of the flag shaggers here having no voice.
