I've been seeing this a lot lately. When in an argument, at some point someone will start quoting the names of logic fallacies, such as ad hominem, straw man, etc. For example:
Lib: We should ban guns because that will stop crime.
Me: You are ignorant if you think banning guns will cause all guns to instantly dissappear. Besides, criminals will still break the law, getting guns illegally or using other weapons.
Lib: Ah ha! That's an ad hominem attack! Your argument is therefore automatically null and void, and by default, my position is automatically correct.
Me:
Someone who is good at rhetoric will use logic in different ways to make their point or break the other person's point. Quoting logic rules usually means that they just learned about them from a website or in english class, and have a rhetoric hardon that they are just itching to use. It also shows that their argument has no real substance, besides, quoting logic fallicies is in itself a straw man attack.
