Think of people as blind ( as diferent as our opinions are, and as convinced we may be of anything, there is no viable way of proving without a doubt that any of the things we believe in are true...belief is not only in religion and proven facts may be proved wrong any time ) blind people will always need a walking stick , a reason of existance (even if this implies accepting that your existance has no reason , it still in itself constitutes a reason of existance ) some people call this religion others call it science, others love, it iis all the same so long as it's meaning remains true to the person.
The main dilemma here is not belief or religion(believe it or not) but dogma.
When agroup of individuals are deprived from the right to decide what is meaningful to their existance and/or are imposed the belief in something, theyre freedom is narrowed and thus conflict is generated and dogmas appear. groups of individuals function upon conflict of interests (at least in our society) and thus dogmas of any kind play a very important role in the exclusion/inclusion of certain individuals in our society, think about it, this is why socialism never was and capitalism has thrived to its utmost. The dogmas we swear upon have encompassed such an undeniable part of our existance that we fight to defend them , even if we have not freely chosen them , to freely chose becomes more and more difficult and that is why a rise in religious sects and autonomous groups appears (sects, fraternitys, political parties...), society seems vast and meaningless and these groups present themselves as choices when they really aren't and are defined merely by our situation and standpoint. So the question is really am i able to chose freely? the answer is not as complicated as it seems because if the answer were yes the question would not have been asked in the first place, the choice would have been made before.
In conclusion don't be angry if a person has a different standpoint, this does not necesarily mean that yours is better or you are better...open discussion is the only way of achieving a more open minded frame setting, treat democracy as if it were, when you know it isnt and won't be.
