I think that most people actually define who they are by a set of beliefs. Their individual set of beliefs make them a particular individual. When they start to state
who they are, they say things like I am religious, or spiritual, or could never do this or have that because I believe..............????????
I find that it is very rare to find anyone who can seem to step outside of their often narrow
belief comfort zone to actually meet another individual on a different set or level of beliefs, and therein lies the problem.
Personally I find that having a particular set of beliefs is often very limiting on all levels, so I try not to confine myself and try to accept everything as being ok or possible or worth trying, at least once, so long as it does not appear to damage a person physically, psychologically or philosophically.
We are all limited, even with ever-changing-beliefs, sometimes very limited, and that makes it almost impossible to co-habit with anyone, or even to get on with some, on a daily basis, on even the most basic levels. JMO
