Well said and I thoroughly agree. I read a post a few days ago arguing to the contrary; that even those who dress to impress can be scoundrels and since most are too thick to notice grammatical accuracy, what does it matter? If we all took the anything goes attitude there would soon be no recognisable language to share.
If one is too thick to know the difference it is easy to think that they have missed something in their appraisal of the sources they read from, isn't it? Breitbart was the quoted source. This isn't just about looks, it points to their ability to evaluate content.
