Protection for the “privileged” is long gone
You use historic censorship as proof that trigger warning protection exists today for certain privileged members of society. Those protections were wrong and are now long gone. Anyone who leaves home, turns on the television or reads a newspaper is now confronted with sights and sounds that might bother him or her. Last evening, while watching a major broadcast network program, I saw a commercial for a national jewelry chain. The commercial was selling engagement rings. It showed two women getting engaged and having a wedding. There was no trigger warning. I do not care for vulgar language, yet there is no warning before someone blurts out an f-bomb in public or slips one into a Medium article.
Deliberately offensive speech is always wrong and the speaker should be called on it, whether the speaker is a neighbor, a co-worker or a politician. Restricting speech is un-American.
