@zahira - what you are explaining is a concept embodied in British law (and therefore most British colonies law) known as the separation of church and state.
This concept allows that there are laws which define what is acceptable or not in society. These laws dictate what is to be penalised and are not supposed to reflect on personal lifestyles. They are supposed to be general principles that ensure a society works and that people have a way to resolve debate concerning personal beliefs. That is, the law should be a neutral and unemotional arbiter. Similarly, the accepted understanding within this separation of church and state, is that individuals participating in that society will reciprocate and not prosyletise their personal beliefs on the society.
Unfortunately we have come to a situation in the current world where what is termed "tolerance" for beliefs means that those laws are able to be usurped because a person says "this is my belief so you can't penalise me". I'm sure everyone thinks that reasoning is false however, at this point in our societies, it is difficult to tell people that something they are doing is unacceptable or outside the intent of the law when they couch it in terms of "personal belief". We are now at a point where we become militant in prosyletising our beliefs and are actually inflicting them on other people by law.
I am not for or against religion, or anyone's choice of lifestyle for that matter, I'm simply trying to show that while your thoughts are noble and essentially what all people would agree on, the creation of that attitude and motivation in a society is more complicated than simply stating that is what should happen. A good example to explain this is the issue of "rights". How many people who say "this is my right" stop to think that if I have a "right" to do or think something then the next person also has a "right" to think or do the exact opposite? And if I don't want them to bother me then I shouldn't bother them?
On the surface we might say we think these things but our society and history prove we don't actually believe or practice them. The more someone says the opposite to our perceived "right" the more militant and aggressive we become. We become so emotionally involved with our beliefs and our "right" to our beliefs that we forget to analyse what other people are saying, admit the possibility that we might be mistaken (or need to change anything in our own life) and therefore take everything as a personal attack. This gives us an excuse to become offended and therefore militant in our "right" to our personal beliefs.
An interesting aside to this is that we often get involved in discussions such as this one to prove how righteous our beliefs are by saying that we are so tolerant of everyone else's beliefs. We state things like "everyone has a right to their own personal beliefs" or "their personal beliefs are none of my business" as if this is some wonderful new thing, never before heard, that we are now proclaiming to the world for the good of all mankind. Actually in doing this we are simply trying to make ourselves look good and tolerant. Unfortunately reality and history prove that when it comes to other people's lifestyle choices coming into contact with our own lives we react very differently to these proclamations of righteousness (I include myself very much in this category).
Personally (*recognises the irony in the statement "personally" and put's tongue firmly in cheek*) I think we should forget bringing this up as an issue. Leave it alone and just shrug our shoulders at someone else's belief. There are laws which say don't kill, don't steal, don't hurt, etc etc, these are universally accepted as a good idea, anything outside of those laws is a non-issue. Anyone demanding recognition of their beliefs or of their championing of other peoples rights to personal beliefs is just looking for attention and for people to say how great and righteous they are. Think about it.... these are supposed to be our personal, private beliefs.... go home and practice them in private and stop trying to politicise them and show off.
Also, be willing to accept criticism and the possibility that we may just have something incorrect in our beliefs. Don't be so self-righteous and bigoted that we think only our belief, opinion or righteous proclamation is right and that nothing can be improved in our approach and lives. Actually it could be possible that this is the key to solving the issue....opening our minds to the desire to change and improve our own beliefs and motivation, rather than making proclamations of how tolerant we are to other people's beliefs. This would be very hard to dictate by legal document.
