In fact even new writes mistakenly use them; but professional speakers use them intentionally to throw off audiences.
It means Deceive in Latin.
5 common Fallacies are: Ad Hominem, False Dilemma, Red Herring, Slippery Slope, and Straw man.
An Ad Hominem is always an argument against the other person. See video for more.
Next is the False Dilemma : Provides someone with two extremes to choose one being obvious and one being worst case scenario.
Red Herring : to distract someone from the argument by using irrelevant details.
A Slippery Slope makes an argument that you'll make bad decisions after bad decision.
Straw Man: Makes an opposing argument weaker than it is to shut the argument down easier
