I’m going to venture to say that a lot of the people you speak of are not actual Christians, but rather those who engage in “churchianity” because it gives a veneer of authenticity to their very human biases and shortcomings. They are not interested in the love of Christ as much as they are interested in having “bought” the right insurance plan — one with a enough wiggle room to still let them indulge their greed and hatred.
And it’s also my perspective, as a former Christian, that the darkest parts of this dynamic come from the lack of masculine/feminine balance. If everything about the society you live in/worship in is geared around a patriarchal dominance hierarchy where you must always be stepping over others to get to a higher place, no true generative spirit can survive — generative energy is inherently feminine in nature and if you constantly dishonor and undervalue anything that is feminine, you can never truly embrace this aspect.
Jesus was a prime example of masculine/feminine balance (as in yin/yang and not just male/female). He stands in sharp contrast to the patriarchal God of Abraham. Those who cling to a God of law instead of the grace and compassion that Jesus brought do so intentionally. It better serves their human foibles.
Until such time as we return to a spiritual tradition that supports this kind of balance, we are going to be stuck in dominance hierarchy where someone else has to lose in order for me to win; where we devalue the poor and victims because from a hierarchical perspective they must deserve to be there on some level; where we feel that if we have power, we have the right to force those around us to live according to our whims because we have somehow “earned” the right to do so. The fact that these people are the modern embodiment of the Pharisees and the Sadducees is entirely lost on them.
