[11th grade in College level English: Persuasive speech on a political subject] How can I finish this?

Here's my professor's guidelines: "Topic: The speech should be on one side of a controversial issue from the list provided below. This means that you are to take a stand on the issue. You are to talk about something that you believe we should do, not do, think, or change. Choose a topic from the list that (1) is relevant to your audience, (2) can be brought down to an action or position/belief that we can adopt, and (3) an argument can be presented in three to five minutes."

I just need some advice and opinions on my speech so far and how I should finish it! Any criticism helps as long as you remain respectful as this is a political and seemingly sensitive subject.
