Im an idiot for saying people who purposely correct you on the blockland forums are annoying pricks
No; he utilized inductive reasoning in the form of an argument from signs to make the call that you're an idiot. Let's make a list of signs:
1) Failure to be able to construct a valid English sentence
2) Failure to be able to spell basic words
3) Failure to construct a valid syllogism about presidential power
4) Loose grip on current events
5) Self-centered view on social interaction (i.e. don't do x because I don't like it)
Conclusion: you're mentally a child.
So, let's do one more round of reasoning. Someone who is mentally a child is one of two things.
1) Actually a child.
2) Low IQ, as IQ is by definition the ratio between mental age and physical age.
So, you're either a young child or an idiot.
