Do unto others as you would have them do unto you

Isn't that such a beat around and oft-repeated phrase ? We hear this so many times that I feel it has lost its value. Once upon a time, I was accused of breaking this rule of life but I am glad that at that time my friend pointed this out that I was not treating others right; I used to make fun of people but could not take it when the position was reversed. I find that people who try and uphold the "morality" banner (the do-gooders) break this law often. For instance, I know people who would hate to have others get physical with them during a joke but then those same people wouldn't mind getting physical with you. All I would say is that try to at the very least nto do what you are doing but if you can not do that then do not get upset because someone is giving you a taste of your own medicine. Try to put yourself in the other person's shoes for an instance. I am against even those people who defend themselves by saying, "Hey, that person does not mind I make fun of them."
Yes, and your point being?
Look, if you do not like something yourself then don't do that same thing to others regardless of whether others mind it or not, that is just plain wrong and to all the do-gooders (not that being a do-gooder is a bad thing) do you not stop to think for once that this goes against all you believe and uphold?
