Fallacies of Assumption
What is Tu Quoque ?
This is literally translated to you too. It helps you avoid having to engage in criticism by turning it back on the accuser. Answering criticism with criticism. This is committed when it is assumed that because someone else did something there is nothing wrong with doing it.Saying someone's claim is false because their past doesn't match their claim.
Why Tu Quoque is Wrong ?
This is a fallacy because both people could be in the wrong and two wrongs don't make a right. The actions or person's past often has little to do with the person's claim at the moment.
