This is a childish argument that because you misspelled a word or punctuation your entire position is invalid. This error is made by people not smart enough to detect there B.S. and people that can’t evaluate the content. It is usually made by young people and anti-theists posing as older than they are. It is a behavior they recently picked up in grade school, the only place where this argument is valid. The person making the argument is emulating the behavior of the teacher and is forcing the frame that they are dominant in the relationship. Whereas if that were the case they wouldn’t be using the fallacy because they would realize how childish, and wrong it is.
