Is it not time we have a second look at religion as it has led to dogmatism and bigotry and caused misery?

Religion was supposed to bring harmony but what we see is chaos. Every religion advocating its superiority. Why should we have such a thing that brings only disruption in our lives. Why temple ,church, mosque. Why make it communal? If one needs religion why it should not be personal to him, with no name tag. Is it not time we have a fresh look at something that goes by the name of religion and failed to achieve what it was supposed to achieve--- love ,peace, brotherhood.
