I think it's possible to be a legitimate pacifist and argue against supporting Ukraine fighting back. However, you go beyond that. You pretend that somehow NATO and Russia are morally the same; you deny that one is clearly far less undemocratic than the other. When you go around saying how America would like it if Mexico or Canada were to join an anti-American defense alliance, you are creating a false equivalency between NATO & Russia. They are not equivalent. One is more democratic than the other, and so is morally superior.
