1st Debate Team Speech PLEASE READ I NEED HELP

Hi! My name is Lilly I am 16 and starting debate team next week. This is my first ever draft of my speech. It really isn't a speech more of like an outline of what I am going to say. It is about gay marriage, even if you are dead set against it please read and give me reasons why you are. And if you are for it please give me reasons why. If you have any suggestions about my writing please comment. I really need help, all the members of debate team are male and I really do not want to seem like some idiotic girl who just joined for fun. I want to be heard and I want to get my point across. Please, please, please read! Thank you! Please comment on the article not on the forum I don't know how to get back to the forum. Thanks again!
