It used to be Don t have sex. Well, you shouldn t really have sex, but if you do, you should use a condom. Now we say things like, I don t agree with that lifestyle, but I wouldn t want to offend anyone by saying so. I think that we have a consensus on murder. Everybody can agree that s wrong.
People rationalize and justify all manner of bizarre, deviant behavior.
I ve heard people say that a rape victim deserved it. Or that stealing from an employer is OK because they don t get paid enough. Of course, it s perfectly acceptable to cheat on your taxes. Everybody does it. Either that it s not very important or that the adults around them are not really very serious about it.
