Why is the h word the d word the sh word the f word BAD words?

Answer 1

Each of the words that this question hints at are not 'bad words' in fact their usage is Constitutionally protected in the United States and many countries around the world. The majority of people have developed a system of government called a Democracy, this Democracy allows the majority to act, even if in violation of rights, to enforce whatever laws or rules they decide. This "Majority" has pressured society, lawmakers, regulatory bodies, and other forms of government as well as online content providers, to bend to their will and classify some words, types of speech, and its expression as "against the law," "Obscenities or Vulgarities."
