Audience is very important. You must change your presentation/speech to adapt to who is listening. Personally, I would like to talk to people who are open minded, respectful, and good listeners. However, this is not a perfect world, and therefore audiences may not be so uniform. In giving a presentation, you must appeal to the audience by letting them know why something matters to them. For example, if you gave a speech to elementary students about inequality amongst genders in the workplace your words will go in one ear and out of the other. However, if you go to an LGBTQ parade and preach “It’s Adam and Ever not Adam and Steve”, you will have an engaged audience, but not one that you would convince.
