It’s interesting how “populism” is bad, but “democracy” isn’t.
I don’t know what populism is, but I know what nationalism is. People throughout the western world have had up to their ears with unvetted outsiders being allowed by their own politicians to invade their country and then having to provide for them and put up with their crimes and having to change their own values to accommodate the invaders.
People want to regain control of their own countries, and not be insulted for wanting to do so.
