Disagreement about perspectives, opinions, etc.—implies there are different perspectives, different opinions, etc. When there are different perspectives, different opinions, etc., here—diversity is happening here.
I don’t think there is such a thing as “oversensitivity related to intolerance” happening here.
A lack of tolerance for (i.e. a lack of acceptance of) other perspectives, other opinions, other solutions, other techniques, other ways of saying things, etc., can manifest itself in oversensitivity. This oversensitivity implies easily becoming upset or annoyed about other perspectives, other opinions, etc., than your own. Are there people in this thread who were annoyed about others they disagree with? I think there are.
When I suggest the people here to be more tolerant and less sensitive—I suggest them to be more accepting towards other perspectives, other opinions, etc., than their own; and to be less annoyed by other perspectives, opinions, etc., than their own.
There seems to be an irony here. Because of the arrival of new people here (being celebrated as an increase of diversity), there is a discussion here which, at times, suggests a lack of tolerance or acceptance for other perspectives, other opinions, etc.
