This can help prepare for the usual arguments. Some are fallacies. If you're not prepared for them, they can throw you off. I'm not always good at responding intelligently in an argument. Over the years I've learned good responses to the typical arguments. These memes actually consolidated a lot of the concepts that get thrown around by people who are ignorant to history. Not everyone is going to be completely logical, but if you can slow down some of the parade of ridiculous predictable arguments it will give them time to think about your ideas.
