How do you lovingly disagree with someone when you're really passionate/convicted about a certain issue?
There were a lot of good responses in this thread.
I think your question differs depending on who one is talking to. For example, an on-line stranger you can talk till you are blue in the face and no one is going to change their stance. Also, with a stranger, your respectful disagreement is more likely to be taken the wrong way. With a close friend, one who understands your history, knowledge, heart and where you are coming from, you may have more influence, and they also understand that your disagreement is not personal.
Since you asked "how" I am going to give some practical things that I try and do:
I think it is important to stay calm. Stick to the issue. Provide your reasoning (based on facts, experience, etc.). It is also important to let the other person be heard, and let them know you are listening.
Often disagreements may arise from misunderstandings more than anything. If I think I might be misunderstanding someone, then one thing I will do is tell them that I want to make sure I am clear on what they said, and so I am going to repeat back what I am understanding and I want them to tell me if I am understanding it correctly. Then I repeat it back as I understand it, and allow them to clarify. I think this also shows them that you are listening to them, and that you really do have a desire to communicate and understand their side.
Another thing is to find the commonalities and work from there. It also provides some validation for the other person. Instead of saying "I disagree...." Start by saying "I agree with this, but ......" Or "I think you are right with this...." By starting off positive, it sets a positive tone as well.
Finally, I would say that you will not change the minds of most people, even those you are close to. It is our nature to seek out information which confirms what we already believe and to ignore information which does not. Have your say, but don't beat the dead horse. If it is clear that the other person is closed off and not willing to listen to your side, then it is time to say that "I guess we will just have to agree to disagree", smile, and move on to something less passionate. You have already given your say and planted your seeds.
