How do you tell your friend that you disagree with them without hurting their feelings?

Explain to them that you respect their opinion but that you don't agree with them. Say it in a calming manner and keep the environment a safe place.

Think about how you would want someone else to tell you that they disagree with you. The "Golden Rule" might be cliche, but it's often the best place to start considering others' feelings.

Remember that you can disagree with someone without necessarily saying they're wrong. ("I see what you mean, but ___", "But have you thought about ___", and other phrases like that might make it seem less personal)

Honesty is very important, but being polite is the key. Explain your point of view politely and be very clear about your ideias, but not offending or pointing out how wrong their view is. We all have different ideias, but it's important to respect others

I honestly tell them how I feel, some times they do get mad but true friends will always come around. The old saying Truth hurts and some times we ask and are really not ready to receive the truth.

It's great that you're considering your friend's side in this. However, disagreeing is what keeps friendships and relationships healthy and balanced. When I come across someone with whom I disagree, I simply say that. I say I disagree. We often forget that it is up to the other person to manage their beliefs and their feelings, and not necessarily up to us. That being said, of course going up and saying "wow, you're stupid, that's completely wrong, you're thinking and/or doing this wrong", that would be a disrespectful way to disagree, and of course the person would be expected to feel hurt. But simply saying something like "Have you considered this perspective?" Or "well, this is how I'm seeing things" Or even, depending on the situation, saying something as blunt as "I disagree" are healthy ways to engage in discussion and also get your point across. If the other person becomes hurt and/or defensive, that is something they have to process for themselves. And that too, is okay! We can't appease everyone.

I acknowledge and validate their perspective, ask what makes them think that's the best idea. I let them know the way I see the situation and why. And support them in taking the action they choose for themselves.

Id suggest you verbalise that although you see their point however you dont have he same belief. But respect them

By letting them know that your opinion differs from them and that you respect theirs as long as they respect yours

I would always agree with them first before voicing out my opinion. Then, I will try to gently suggest something from the points he/she mentioned. I will slowly add my point of view to his/her thought. Rather than hoping him/her to listen to my disagreement, reaching a mutual understanding is important too.
