I can't see why this woman would continue to press her claim, risking widespread ridicule, if she had indeed cancelled her flight. And having had a ticket cancelled by an airline without my knowledge (fortunately, they tracked down and admitted the mistake and had a seat available), I can understand how upset she was. United's explanation smells like PR bullshit.
But the true piece of shit in this is Jackson Lee for playing the race card when it was unwarranted. Even if she is innocent (which, I confess, I doubt), she has no right to publicly accuse this woman of racism, and she owes her a very public apology.
"It is not I who is mad! It is I who is crazy!" -- Ren Hoek
"[... it seems most strange that... ] the Creator of Heaven and Earth resorted to the womb of a certain Jewish lady, grew there for nine months and was born as an infant, and afterwards grew up and was betrayed into the hands of his enemies who sentenced him to death and executed him, and that afterwards... he came to life and returned to his original place. The mind of a Jew, or any other person, simply cannot tolerate these assertions. If you have listened all your life to the priests who have filled your brain and the marrow of your bones with this doctrine, and it has settled into you because of that accustomed habit. [I would argue that if you were hearing these ideas for the first time, now, as a grown adult], you would never have accepted them." -- Rabbi Moses ben Nahman, defending the Talmud at the Disputation of Barcelona, July 1263.
"God is the supreme excuse for human adults to absolve themselves of any obligation to preserve natural resources for their own children during their lifetime." -- Gene Ray
