I would agree with Leo Tolstoy that patriotism is just bad. And I do not understand why should we invent a "good patriotism" while the term itself is so bad.
To destroy governmental violence only one thing is needed: it is that people should understand that the feeling of patriotism, which alone supports that instrument of violence, is a rude, harmful, disgraceful, and bad feeling, and above all—is immoral. It is a rude feeling, because it is one natural only to people standing on the lowest level of morality, and expecting from other nations those outrages which they themselves are ready to inflict on others; it is a harmful feeling, because it disturbs advantageous and joyous peaceful relations with other peoples, and above all it produces that governmental organisation under which power may fall, and does fall, into the hands of the worst men; it is a disgraceful feeling, because it turns man not merely into a slave, but into a fighting cock, a bull, or a gladiator, who wastes his strength and his life for objects which are not his own but his governments'; and it is an immoral feeling, because, instead of confessing oneself a son of God, as Christianity teaches us, or even a free man guided by his own reason, each man under the influence of patriotism confesses himself the son of his fatherland and the slave of his government, and commits actions contrary to his reason and his conscience.
