Answer:
People's beliefs about things are based on their own experience, so their perspective on the same thing will always be different to you - they haven't lived the same life you have, so how can they see things the same? From their perspective, given the life they have lived, what they are saying is true. If you state your case, and it differs from their belief, their brain is wired to resist accepting your case, because it takes effort to remodel the brain to accept these beliefs. Just leave it, and if what you said had some truth, then their brain will assimilate what you said over time, and they will unconsciously think over time that some aspects of what you said was always what they believed! Try bringing the same thing up with the same person some time later, and see if their perspective has changed. If the belief is firmly ingrained, it may not shift - but there's nothing you can do about that - it's just the way their brain is wired - and that's not wholly their fault either - it's a consequence of how their brain works, and how it has been influenced through their life. And here's the thing - the same goes for you! Your beliefs will (whether you realize it or not) be influenced by what other people are saying, however much you resist it. If it holds a grain of truth, you will inevitably take it on board one way or another.
So don't sweat it, just let biology take it's course.
