What we think is a simple sharing of opinion can be construed by the other party as denigrating.
In such cases, it doesn’t do any good to try to convince the person that the way he or she feels is wrong. You need to deal with the way the person feels to affect their thinking.
The most effective way to do this is to apologize—-that your intent was not to prompt poor feelings but rather just to share an opinion. Then acknowledge that you accept their opinion—even if you differ with it.
That’s what diversity means.
