using intentionally reductive and simplistic reasoning, like " line goes up ", "which means we will all live in a utopia" as well as taking modern events and changing the details to make a ridiculous position "conduct a huge trek to reach countries like uhh India, China and so on and so forth" (people are in fact not in huge numbers immigrating to those countries, instead are going to the west)
