Media outlets have carried a recent story about an Australian man who flew from that country to Singapore. En route, he became involved in an argument with a fellow passenger and directed profanity at the individual.
The abusive passenger was met upon landing by Singapore police because his language was a violation of a Singapore modesty law which was in effect on the airliner, the penalty for which is imprisonment and/or caning.
I somehow suspect that if a similar law were enacted here, that the American Civil Liberties Union would have something to say about it. I am not going to endorse a prison sentence or physical punishment for those that are coarse, crude, and vile, but I like the spirit of those in authority in Singapore, who have taken some action to ensure a society of civility and respect, something which long ago was sacrificed on the altar of free speech in the United States.
Don't take for granted the little liberty we have left just because you disagree with how some decide to use their freedoms.
