Disliking Plato because he's not "modern" is a little silly. His teachings are obviously old, but they were also a huge stepping stone in philosophy.
And I do not debate his influence on European philosophy, which is hard to underestimate.
Mostly, the reason I dislike Plato is because in school I had a teacher who practically worshipped Plato and acted as if he was the pinnacle of philosophy or human thinking in general.
Also, a few years later, I was unfortunate enough to read an introduction to European philosophy written by somebody who literally said that European philosophers could be divided into two groups - those who agreed with Plato, and those who were wrong.
So when it comes to Plato, I am kind of "traumatized".
What I meant to say was that it took us surprisingly long to rediscover that particular piece of wisdom expressed by Plato, and that given my attitude towards him, I was pleasantly surprised to see him express such a thought.
