Translation: Please, allow me to rant about grammar.
My reasons for disliking the misuse of the language are many:
Firstly, English is a language. Language is a form of communication. If you are not speaking the language correctly, then the intended receiver of your message is instead receiving utter nonsense and a headache.
Unless, in the case of special discourses (lolcat, txtspk) the receiver is also fluent in this language. Then you may “Can I has” all you like, all day long.
The problem comes when someone is attempting to communicate a complicated message to someone outside of the discourse of their language. For example:
I can has life? I r livin? I r thinkin, therfor I is! It simpel!
