The Golden Rule

I was reading the Deseret News a day or two ago and glanced at the reader's forum. This is the part of the newspaper where readers can write in and give opinions. Well someone wrote in about the golden rule. They said that because Mexico is so aggressive with immigration (deporting and giving jail time to those illegally in Mexico) that we (the U.S.) should follow the golden rule and act equally aggressive towards illegal immigrants here. I wondered if the writer realized that what they were describing was close to the Law of Moses and not the golden rule.
The golden rule is that you should treat others the way you want to be treated. It is a rule designed to let your example influence others and thus cannot be applied in the reverse way - to treat others the way they treat you. That is the Law of Moses provision of an eye for an eye and a tooth for a tooth. It works by making people fear the retaliation they will receive if they wrong you. I must state, though, that this particular comment wasn't even strictly Law of Moses, although I'm not going to elaborate why unless someone really can't figure that out.
I really don't mind if the U.S. enforces its immigration laws and gets more tough in this area, but if we do this let's at least not call it the golden rule and lets not do it as some odd punishment to Mexico.
