Be it family members, friends, well-wishers, or a person whose values and mindsets don't match with ours, or any stranger, we should treat them with great respect and love.
But what is the most difficult part here?
It is "To Love Unconditionally"
Love and compassion might come easy comparatively for our friends and families who we very well gel along with, but becomes a challenge when you don't get along with each other and the thought process of one person doesn't match the thought process of other.
The conflict faced due to this mismatch is still a beautiful discussion if both the parties have Tolerance and Broadmindedness to accept each other's views.
Rev. Vivek Shaq Ji once said we should start making our hate-list and besides that start writing the good attributes of the person. Soon you would condition your mind to give a benefit of the doubt to the person who was on your hate list.
You would try to empathize with his situation and put yourself in his shoes. That would help to build your tolerance and acceptance towards his actions.
And, what if after giving the benefit of the doubt, you let go of your hatred towards that person but the other person still holds a grudge against you and probably wants to hurt or harm you?
Satguru Maharaj Baba Hardev Singh Ji gave a beautiful solution to handle a person who doesn't get along with you even after multiple failed attempts, "DOUBLE THE DOSE OF LOVE"
Even if the person is reluctant to accept us, still what is stopping us from being loving and compassionate about him, being tolerant and accept him as he is? As a saint, we need to check Is it our ego that is holding us behind? Because a true saint would never refrain from being loving and caring for anyone in the world unless he doesn't know the God Knowledge and doesn't understand that all are the creation of one God one Nirankar.
