I think that when averaged out, the majority of people prefer semetrical faces, but that does not make the individual assessment of beauty or ugliness any less subjective.
It's a bit like saying it is an absolute truth that everyone prefers carrots to spinach. Whilst the majority of people might prefer carrots to spinach, each individual can still have widely varying views.
So to link back to the OP - whilst the dialect/grammatical errors they used grate on the majority of people, it does not mean that some people will not see them as beautiful. And since beauty is oft said to be in the eye of the beholder, one might assume that these people are more likely than not to come from Essex
