To Respectfully Disagree

It is okay to disagree!

People get so wrapped up in trying to convince others to believe the same thing they do. We absolutely should stand up for what is right and true, but people are free to believe whatever they want. They are free even if what they believe is downright stupid and wrong, and demonstrably so. To respectfully disagree with others gives them the opportunity (should they want to take it) to think through your ideas and voluntarily accept or reject them. Too often, people lose their sense of decency and respect in their discourse. Then, conversation becomes contention, which leaves no room for the influence of the Holy Ghost. At that point, there's no use in any further discussion.

It's okay to simply say, "I disagree." State the truth, and leave it at that.

As a side note, some people use the phrase "agree to disagree". That actually kind of irritates me; it makes me think of something like this:
Bob: "All right. When we go in there, I'm going to say one thing and you'll say another. We'll make sure to disagree."
Susan: "Agreed."

Last thoughts for now:
The Golden Rule is key here. We're all struggling through life and eternity, and we ought to show charity for others, even when we disagree.
