It is an emotional appeal. Which 1) insults my intelligence, thinking I'm stupid an unaware enough to fall for that. And one or more of the following 2) you're too stupid or poor at arguing that you don't know you're doing it 3) the facts don't support your side so you try to rile up the ignorant and gulliabl to win 4) you don't care about argument / have other motives like fame, clicks, distraction from other issues.
