Disallowing beauty pageants is a violation of the First Amendment End of argument. Members of the Westboro Baptist Church are allowed to express themselves, although their words are entirely hateful. Anyone and everyone has the freedom to choose what they want to do within legal realms. Banning beauty pageants would be a sad attempt in the name of political correctness. Would we ban tomatoes from being consumed because some people don't like them? Our nation is becoming so overly sensitive.
Appropriate isn't the word I would choose Kylie Jenner has the freedom to do whatever she wants. She is a legal adult. What is your definition of appropriate? Knowing this would make it easier for us to determine whether or not we agree with the question asked. People have different definitions of what is appropriate and what isn't.
