I do not think it necessary to define a chapter that properly refers to the field of religion. In everyday reality, everything that is included in this concept is limited to a set of customs and traditions that each individual adopts in his particular way (a Catholic / Christian / Jew / Muslim goes to war to kill, something that is usually Others drink alcohol, consume or sell hallucinogenic substances, live for wealth, while others die poor, lie, steal). There are people who do not believe in anything, but who assume the characteristics of the people who founded those religions.
It is not possible to nullify the beliefs, we all believe in something, philosophy of life, ideology of coexistence, religion, nature, politics, sports ... whatever. What should be considered is a respect for each identity of each person, should not be coerced. But if you protect yourself from aggression and respect the other in how you express your individuality, what you believe you can bring to the community so that it grows and improves, for a common good.
I could assure that at some point we will find ourselves in the dilemma of breaking with anthropocentrism; Because we could realize that our planetary companions (animals, plants, etc) are not far from having the same abilities as ours (not improbable), only that they are handled with different codes; So we will also get to the sigularity with the technology, certain type of machines will have our same capacities. And if we are lucky (or bad luck) we are not alone in the universe. In either case many certainties that centuries ago between us would collapse
Well there is an observation I hear from the Kyril Orthodox, which impresses me, because it is quite accurate (only a fragment of it, LOL). In some countries the "secular / lay government (without religion)" (I believe that in the end almost none is, since in the laws appear many sections that seem religious) are created laws of religious equity that end up causing more friction between the Different confessions (like Christians against Muslims in Europe), and some end up not having the same freedoms as the other for example: bathing clothes (europe, australia), Christmas festivities (near east); But there are other places where there are 10 religious expressions and live in respect, animists, atheists, Muslims, Jews, Christians, Buddhists, and so on.
Going to the idea. Is inappropriate to use the term religion/feith/ideology/cult, it should be: Personal cultural-ideological expression, and it must be protected and limited in all the terms of reason and coexistence. The nation should not submit to repressing expressions, but believers should not impose their beliefs, in that case restrictions may be placed on individuals who do not respect others (not the profession of religion, nor an ethnic community); Must participate under the ambit of logical-practical reasoning and complete fraternity with the community
