This was a lesson I will never forget as you can use it in more than just your writing, but also in arguments and other things. Just remember guys women are always right, at least us men get the last say in all arguments with women: "Yes Darling"
As we know we all do not think the same way. By adding these opposing view points in your writing is not a bad thing. It also shows your reader that you understand and have done research on your topic.
You might think that putting opposing viewpoints in your writing is a really bad thing, as you want your reader to agree with you right? This doesn't just help the reader know you understand what you are talking about, it also helps with your credibility as a writer. This also gets the respect from your readers and they will listen to what you have to say.
State it right, state the argument and that you do not agree with it.
Make sure that you are arguing or presenting a point that is valid for your statement and purpose of your paper. If you arguing that fast food is good in a diet, but your counter view is about global warming, well that isn't going to help you prove your point.
When you bring up the opposing view, address it then answer it with something to back your point of view up. Also state who is the author of the counter argument.
Remember not to seem as if you are fighting with yourself, that is weird, and your reader will get confused.
Just on a little side note for self improvement. I will be doing 1 push-up for every 1$ earned on my posts and will give a short feedback every day at the end of each post. As promised I will be doing 73 pushups, today, for yesterdays post. Any not done will carry onto the next day. 20 is carried over to the next day.
