The difference being that I explained what those beliefs were and didn't try to claim them as realistic. My example of movie quotes is one that in particular proves my point about them being unreliable at best and an utter pile of garbage at worst.
I actually went on to accurately explain the belief rather than just saying I believe this and never replying. Again movie quotes are often never backed up to begin with. There's the difference.
See, the difference is that they're not taking the example of philosophy from a movie quote, they're using it as a way to sum up their argument. Plus, movies can be as philosophical as comic books.
Even Star Trek points out that conflict is good - conflict is what drives people to do things. Man Vs Man, Man Vs Nature, Man vs Self. Pure good is just as bad as pure evil, because pure good is stagnation and lack of desire to advance. See, perfection is a horrible thing, as it prevents any attempt to beat perfection - your perfect isn't everyone elses perfect.
For that matter, you even acknowledging your belief's aren't even realistic proves that they're horrible, horrible beliefs to have. Sure you can think people are intrinsically good - but if that prevents you from acknowledging that people act selfishly and like assholes and that'll fuck shit up (Like you do), it's a horrible belief to have.
