Question

Why is it possible for people belonging to same religion to feel That they don't belong to same community

Answer 1

A community belongs to a group of people in a society of the same caste,creed,religion etc.

If a person from the same religion comes to the community, the community people will differentiate him through his caste or sometimes gender.

Even the lowest caste can follow any religion depending upon his/her devotion to the particular God.

So due to this differences a person belonging to same religion will feel that He don't belong to the particular community.
