According to me, in every religion there are Fundamentalists, who think that their own religion is greater than that of others...Here lies the Toxic problem.
Since history we find that in every religion there were some Religious preachers,who tried to rectify the rigid norms of their scriptures,as well as the drawbacks of their religion. viz : Goutam Budhha, RamkrishnaParamhansaDev, etc. they didn't say to follow the strictly rules of an ancient religion,rather preached some non-violent,user friendly(!) ways to get peace.
...but surprisingly, in Islam there is none, after Mohammad, to reform the orthodoxy of Islamic cultures/ oppression of women in every field...
Self -evaluation is necessary for every caste to form a Modified Peaceful society!
