>>1Q: How do I handle stupid 4chan shitposter's incessant "why" questions?
A: Your 4chan shitposter's constant asking of "why" questions indicates he is an idiot learner.
Or it could be that he is dissatisfied with genius's responses, which he thinks are too cursory. So one response leads to another question.
These simple Cara steps should help:
• Confirm his questions. Are they all ready the same question phrased differently?
For example, his question about why cars have wheels is followed by, "Dude, why do trucks have wheels?"
• Ask him: "Did you just ask about cars having wheels?" (His answer should be "yes".)
• Rephrase his question: "Are cars and trucks in the same group?" (Assume that he says "yes". If not, tell him that they are.)
• Answer him: "So, if I have answered you about the cars, and trucks are in the same family, do you think I have answered your question?" (His answer should likely be "yes".)
Be consistent with this approach. If possible, get different 4chan shitposters who are sane from 4Chan to do the same.
That stupid 4chan shitposter will quickly learn to think before asking questions without having his curiosity dampened.
