What is idealism?
It is just ignorance of a part of reality.
I used to be an idealist. But I’m not anymore because anyone who understands idealism knows that is it is delusional.
However, it is often thought that idealists want to make the world better and realists (not getting into pessimism right now) want to keep the status quo. That is so wrong.
I am a realist who believes in utopia and is working towards it. Get that.
