Yeah, people try to push this patrotism = good, nationalism = bad thing, but it is meaningless, because patriotism has long since become what Reinhart Koselleck would call a "Grundbegriffe", basically a universal term which everybody has accepted is good, but which everybody interprets and uses in a variety of different (and clashing) interpretations. It is a term you use to invoke that you are on the right side, regardless of what side you are on, because it just means "good".
