Since segregation laws did not provide equal protections or liberties to non-whites, the ruling was not consistent with the 14th Amendment. The others contradict the initial question in one way or another.
A logical fallacy is a flaw in logical reasoning. There are numerous flaws in judgment. One example is the "ad hominem" fallacy, where instead of arguing a point, the person attacks the person's character. Ex. "We should ban cigarettes." "Why should I agree with you? You smell really bad!"
Another example is the "burden of proof" fallacy, where a person who makes a claim states that it is up to the other party to disprove them, rather than prove their own statement. This is fallacious because the inability to disprove something doesn't automatically mean that it is proven. Ex. "There is a teapot floating in between Mars and Earth at this very moment. Prove me wrong!" "I can't do that, because I can't go to space right now." "Therefore, I am right!"
It might be stated that Mill employed a combination of formal and informal tone in "On liberty..", by developing some complex ideas, meanings and expressions. The author used metaphors and figurative languages to appeal to the audience. It might be added that Mill wrote those who agreed with him and he discussed his thesis by attacking the conservatives.
He used frases such as <span> "no one's idea," "no one should assert," "it would be absurd," "nobody denies" . </span>
