How religion separates people based on ideology and belief system

Someone wrote in Yahoo Answers:

"If you are not sure and convicted for what you stand for, you will and can fall for anything. I cannot see, anyone, man or woman, having encountered and experienced the Love of the Lord Jesus, can attest to the salvation that they received and have had a genuine touch from God, easily go into a marriage with someone who is against Christ's diety, His Person and Work" 

The above quote is an example of how the Christian religion is separatist, elitist and sectarian in nature as it divides people based on their ideologies and belief systems. Those who adhere to the Christian religion are often divided over doctrines and may feel pressurised into pledging allegiance to whichever sect or denomination is preaching doctrines that align with their personal beliefs (and bias and prejudices). It is almost as if they fail to see that such indoctrination has made them self-righteous Pharisees who use their religion to judge and condemn other people for living and making decisions that offend their sanctimonious religious sensibilities. It could also be that they are living in their own prison of fear as they are afraid of "displeasing" the idolised god of their imagination, and they are projecting that fear onto other people. 

On a similar note, here's sharing a short story "A Father, A Son, A Cigarette, And Jesus" by Mick Mooney, which does a good job to illustrate how some people in the Christian religion typically use guilt and shame to control and manipulate others to try to make them conform to their socio-religious norms.

Angry preaching comes from angry preachers

 "Angry preaching comes from angry preachers. If you attend a church where the preacher fusses and fumes and yells at the congregation you should consider leaving it because you the listener are not being respected. No one should be yelled at. Respect yourself and your family enough to not subject yourself to it.

If you want to snuff out the flame in someone's heart, tell them what the Bible says about their mistake. Tell them "I told you so!" Tell them how God hates what they did. And when you're done you will have taken what little spark of a life there was left and turned it into a smoldering ember nearly extinguished" Scott Livengood

Judgment and condemnation always kill life whereas understanding and compassion will always nurse life back to health.

 "A preacher can be disrespectful without yelling too. Those are the sneaky ones".EDK

I  agree with Scott Livengood, Skip Newby and EDK - angry and/or disrespectful preachers are to be kept at a distance for the sake of our peace and dignity, so that we are not subject to their abuse. We would rather be where there is gentleness and compassion instead of judgment and condemnation. The letter (literal interpretation of scripture and law of telling people do's and don'ts)
kills and condemns, but the Spirit (symbolism and unconditional love and grace of unveiling our true identity of beauty and perfection) gives life and builds people up. May we continue to follow the
unforced rhythm of grace and rest in the kingdom of heaven within,  even as we love the religious people from afar.

 For myself I can say, that if there is a God, and he is such a being as [the Universalist] describes, I can bow before him and give him all my heart. He says God is love, made the world in love, and in perfect wisdom, and well adapted to serve the divine purpose.

He then made a family, all of them have sinned, and some of them have fallen very low, but God is determined, according to [the Univers alist], to stand by His family, every one of them, let come what will come, till he makes all of them respectable.

This standing by His family, as every true Father ought to do, is what I like in [the Universalist's] idea of God. But if there is a God, and he has created a family and will at last turn against most of them, and in burning wrath cast them into Hell forever, as [traditional Christianity] describes, I should hate him—he is not as good as I am, for I propose to stand by my family and every member of it for as long as I live. It is an insult to ask me to love and worship a God who is guilty of doing what we would detest in an earthly father. –Robert Ingersoll

 Yes, like what Robert Ingersoll said, a loving God (according to universalists) is a true Father who loves his family unconditionally and stands by them come what may, and is worthy of our worship and admiration. But a vengeful god (according to traditional christianity) who consigns most of his family to eternal torture is not worthy of our attention and respect - I would say that kind of god is only a mental projection of the human ego or shadow.

We know that Jesus came to reveal who the true Father is, for we who has seen him has seen the Father - one who is kind, gracious and compassionate. We also understand that those who hold on to the idea of a mean, vengeful god are also mean and condemning to others because that is their worldview that causes them to behave that way. Hence, Jesus had prayed for the Father to forgive such people, for they knew not what they were doing, for indeed in their unconscious state, they did not know what they were doing. They probably didn't know how much harm they caused when
they quoted bible verses to judge or condemn people because they thought they were serving god, when actually they were serving their ego. (Paul used to persecute others thinking he was serving god, until he encountered the grace of Christ.) As for us, we will continue to be as wise as serpents and as gentle as doves when dealing with religious people,
