Is it ethical to have a private agenda when preparing a speech? ?

Question

What would be some situations where it would be appropriate to have a private agenda?

Answer 1

i don't get the problem. a speech is used to inform other people about your agenda, what  you think about the topic, how it makes you feel, etc.

Answer 2

sales approach - introducing a new project

elections - why your the best candidate

promoting a project - prospective contracting

almost any situation when you are trying to convince  a group of people that your product or service or idea is the best.

the whole concept is "Selling Yourself"
