Cult of personality -> fascism
Shakespeare for example has been a very typical symbol of british "pride" which is one of the main roots of fascism.
But yeah, sure, it's not the worst one. The problem here is this fascination that people have for historical figures, where it doesn't matter whether you know the work of Shakespeare, what matters is that you know him and how he looks, as the post shows.
Why do you think Trump supporters have no clue what he actually did does ? They don't care because they follow the person, not the act.
When you start worshipping people, you never end up in a good place.
