Right & wrong, according to who exactly?

I wonder sometimes what the thought processes are of people who see things with different perspectives. Are they a reflection of who we are, or of who we have been 'allowed' to be? Hope that makes sense, coz it does in my head.. Also, do the thoughts generate from memory where we've experienced things that help us know or choose to deal with the scenario, or are they generating from logic based on societal norms? Basically the scenario is two people, or a number of (for argument's sake) that wholeheartedly believe their version is the only version and it's the right one. Assuming they all have different versions, their thought processes are all based on different material so to speak as to why they don't agree. So then is it safe to say that in their own minds, they are all individually right according to their belief system on certain things? And if so... then who is another to challenge that? Because in theory, there's no amount of convincing to come an agreement.... it's different perspective. And in that case... all unfortunately I guess, are right. So where is the problem.....? And what is the point of this blog...? The problem is........ that not everyone in the circle of disagreement is comfortable in this reality and in the principle of agreeing to disagree.... Not all understand that perspective is exactly that... its perspective, and if we don't share each other's - that's all that needs to be understood... No harm, no foul. ..........In theory......
