The above statement is not a guideline for addressing your audience. When there is need for an audience to be addressed, there would be a stage in which the person who is the speaker would combine his or her various points into a summary in-order to capture the various differences among the audience.
<em>For example, on boarding school, the speaker should be able point out the advantages which is for audience in support of it as well as the differences (for audience against the idea) before pitching his summary on which he or she stands. This is more realistic rather than, trying to address audience separately.</em>
