Religious belief Vs Humanity

When all religions impart peace ,then why can't we still achieve peace at all.

There are flaws in every religion.....all religions at one end teaching the way of life other end they are teaching negativity pushing to impart fear in people's mind.....there is stress in human life from everywhere.....from family friends society religion social status,social security etc.

We forgot that first we are human than we are hindu, muslim,sikh,christian, jain north indian south indian east indian ,foreigner..
