This has always made me smile:
“If you attempt to tell a relativist the difference between right and wrong, you will no doubt hear, “None of that is true! We make our own reality!” If that’s true, and we all create our own reality, then our statement of moral accountability is merely a figment of the relativist’s imagination. If a relativist has a problem with a statement of absolute morality, the relativist should take the issue up with himself.”
I apologize to the author/speaker.. I have no idea who said that
