What are the similarities and differences between nationalism and patriotism?

The similarity between nationalism and patriotism is that people belonging to this group love their homeland. She is above all for them. But. patriots do not divide people into nationalities. For them, the Motherland is above all else, they are ready to give their lives for it and they do not care. who will stand next to them, even a Dagestan, even a Chinese. But for a nationalist, this is important. They are fighting for the opportunity to live in a country where everyone is of the same nationality. It is impossible by definition. There are no people with “pure” blood. Each of them has more than 10 nationalities in their DNA.
