Things I want to know about argument essays

Should there be alittle if any opinion in them? As in would it decrease the strength of the argument if i threw in an opinion of my own that isn't backed up by a reliable source? Is there any such thing as to much information for an argument essay?

Audience

My audience for my arguement on abortion is against the pro-choice opposition
18yr girl, Derika got pregnant during her senior year of high school with her boyfriend, he got scared and left, not she's scared about having to raise the kid on her own while trying to get into college.

Arguement

Well, the last arguement I was in, wasn't exactly a serious arguement, it was me and and a buddy of mine from the dorms, argueing back and fourth over who was stronger. Well, it started off like just the typical I'm bigger, I'm stronger. And then somewhere in this half hour arguement i blurted out even an elephant is scared of a mouse, and I'm one badass mouse. That right there basically ended the arguement, everybody was laughing, my buddy, me, the other guys who were sitting here. Everybody in the room laughed for about ten minutes.

I had a comparison fallacy, that ties into the subject change fallacy.

Fallacy

The fallacy that I tend to see most often, would be either the authority or popularity ones, mainly because through the media. The media is everywhere and they follow popularity and authority very closely, so whenever you turn on the television there's always something related to either or within the first five minutes.

Personal Essay

The things I liked about my personal essay, were that I was able to write about what ever I wanted to, and I that there wasn't any research that I had to do along with it, because everything that was to go into the essay was all from me. The only thing that may have been alittle hard about writting the essay would be choosing the things that have changed in my life, or that has been there and shaped how I turned out, because there have been quite a few different things I could have said. But, all in all I think I chose the three best out of any of them.
