There are times when you will view a situation from your individual perspectives. Sometimes, it is not important enough to even bring it up. If you feel that you want to talk about, it is better to use the phrase “I see it differently…” rather than “I disagree”.
Essentially, they are saying the same thing. But “disagreeing” has stronger negative connotations and may trigger defensiveness, dismissing your view or even hostility. Adding the word, “I respectfully disagree” or “ I somewhat disagree” still has the word ‘disagree’ with all its connotations.
Other ways of saying “I see it differently…”: “I have a different point of view”, “I have a different experience with that”, “The way I see it …”
