What direction the sun rise is not binary, unlike if a statement is derogatory, the sun can rise in the east, north east, South east, North or south.
If the claim that the sun sometimes rises in east is true than the claim that the sun always rises in the east is false and so is that the claim the sun never rises in the east.
If the claim that illegal is sometimes derogatory is true then the the claim illegal is always derogatory or never derogatory is false.
