Quote editing just makes you look stupider, especially if you use your failure to use correct grammar and spelling on someone that usually uses correct grammar and spelling.
Here, lemme show you an example.
I am a complete dumbass that masturbates to pictures of his grandmother on a daily basis.
Notice how the grammar and spelling is correct, making you look more intelligent than you really are. While the edited quote has a true statement for the person being quoted, everything else is out of place.
