The world is encapsulated with so many religion embedded with different doctrines, teaching and belief which have affected our sense of reasoning in different ways. Religion has raised serious concern to mankind especially in terms of sociopolitical and economic coexistence. The major cause of insecurity in most part of the world today is the problem of economic and religion supremacy where everyone seen to uphold their religion with virtue and in a high esteem and even considered it to be the only true region and the only way to salvation and internity thereby condemning or seeing other religion as fake. So therefore, considering the problem associated with religion differences in world today, I think the world would have be a better place without religion.
The world wouldn't have been a better place without religion because most of them have a good doctrine that promotes peaceful coexistence, equity, and selflessness. The problem we are having is religious fanaticism and religious intolerance. Some people think that their religion is superior to others and have gone to the extent of forcing people to convert to theirs. People have been intimidated, beaten, and in some cases killed because they refused to convert to a religion. It is these fanatics that have caused conflicts and religious wars. With this superior mentality, some religious faithful wouldn't want it live peacefully with others. They think they should have the best while others should be treated like slaves.
Politically religion is affecting the quality of leadership. Most citizens vote for incompetent candidates because they belong to the same religious creed when they have more competent candidates. Religious fanaticism has also led to favoritism and partiality in the appointment of political officeholders and even the allocation of resources. Let me conclude by saying that from my observation, most religion has good intentions, but the problem is that followers misinterpret and wrongly apply most religious teachings.
