To respect others in what they believe can happen only if we understand where our world view came from and the depth of our understanding.
The use of sarcasm, disrespect, ridiculing others only shows our own lack of depth and reveals to others the level of our defensiveness. This shows lack of tolerance and closed heart.
It is always good to study those who have beliefs that are different than ours, as well as those we may think that go against what we believe in.By doing this we learn to listen to others and also develop ways of responding that does not lead to further alienation.
We tend to judge our own religion, faith, political lineage with the best and judge those outside of our system of belief with their worst. This leading us to darkness. "Beware the man of one book" is a wise saying.
Keep the mind young and flexible; keep the heart open and humble. The more we learn the more we learn that we don't know.
"The most beautiful thing we can experience is the mysterious." - Albert Einstein
We should respect our elders. But yes, we should respect every person either that person is younger or older than you.
