Every individuals had the right to belong to any religion or ethnic group they desire.
Using Nigeria as a case study, these terms politics, ethnicity and religion are use interchangeably because in practice they are the same.
Religious bodies are not different with political parties because they are fused together.
All the corruption, money laundering, killings, kidnapping, unemployment, poverty and political instability are caused by bringing religion and ethnicity into politics.
These are the problems of your society, not in any way religion. Religions preach peace, kindness, and love. I think the real problem of the society is the atheists living in it. You have attributed the problems of the society to religion, without explaining to us how religion has caused these problems. You should be able to explain how money laundering and unemployment is caused by religion.
