This week you learned about logical fallacies and how the use of flawed arguments

This week you learned about logical fallacies and how the use of flawed arguments can easily compromise your credibility as a writer. The first step to avoiding logical fallacies in your own writing is learning how to identify them.
For this Critical Thinking exercise, you will find a minimum of two examples of logical fallacies on the news, on the internet, or any other outlet of communication (citing the source of this fallacy as appropriate); you could even make up your own hypothetical example if necessary. As you present the fallacies to the class, you will also analyze them: in other words, explain what the specific name of your fallacy is, and why your example is a logical fallacy. Other things to consider in your main post:
What can we imply about a speaker or writer whose arguments contain logical fallacies? 
Does the presence of a logical fallacy in someone’s argument immediately invalidate their general position on an issue? Why or why not?
