The first logical fallacy is known as the "red herring." The "red herring" occurs when someone is discussing a question or topic, but the other person has sidestepped it by bringing up an irrelevant topic to divert your attention. People often end up debating this alternative, irrelevant topic instead of the original one. Often, people employ this strategy without consciously recognising it. Either the person does not think logically by nature, or it is an inbuilt defence mechanism. Otherwise, it is a cunning diversion to get you off track.
