I suppose ultimately you should read philosophy if you find it interesting. I like talking about philosophy, but find it hard to talk with people who have formally studied it, because they often rigidly cling to sets of ideas that get attached to the people who came up with them, rather than thinking more freely.

I often think it's a little unfair that history and knowledge are (obviously) biased towards people who thought enough of themselves to write their thoughts down.

I'm sure there are a lot of people who could make strong claims on the invention of certain thoughts or theories, but the bar happened to be too noisy for anyone to hear them.
