Fellow speaker,
When giving a speech in front of people who are very different from you in some way, make sure to mention the difference between yourself and the audience in some way to make it clear that you recognize and accept that difference. For example, Darren LaCroix (World Champion of Public Speaking) gave a speech in front of a Hispanic association beginning with, "I have never ever ever ever in my entire speaking career felt so Caucasian."
Making it obvious,
Tim
