Discussing things with people I disagree is awesome!
Reading philosophy books is difficult (for me), because my instinct is to have a conversation, ask questions, explore notions and branches, spend more time on some things than others. It's the railroad aspect of philosophy books (whether I "agree" or "disagree", which is rarely binary), that makes them feel stifling :-/
Even the classics like Plato - or perhaps most particularly classics like Plato - they tend to lose me after the first dozen "As everybody can plainly see...." "We can all agree that..." "It is an understood fact that...".
