You're words are truthy enough, but your assuming that synergistic words like irregardless don't have impacts on english as we know it. The facts is that people will use words like that wether we like it or not. This is truely, the case when it comes to American's use of language. Sadly, theirs very little we, as people far more litterate than the average people, can really do about that. If people used grammer checkers, then you and me would not see so many people authoring bad words and having a negative affect on english as it is known and practised today but should be editted and spokened tomorrow.
