On one hand, we can't expect everyone who goes to church or temples every weekend to be perfect saints.
On another hand, we shouldn't judge a church or temple or religion based on the people we see who attend the church / temple or practice the religion. One extreme jihadist doesn't render the whole of Islam and all muslims as totally violent or illogical.
On yet another hand, if the seniors of a church / temple are consistently treating juniors in a rude or angry manner, then there may some problem with the church or temple. but it is not a good excuse to stop practising the religion. It is up to the observer to check out other churches/temples to see if such behaviour is present there.
If we let a negative incident stop our practice, then we are the ones who lose. Rather than seeing something negative and judge, complain, but do nothing about it, take action and responsibility over your own spiritual growth.
Its funny how so many people can tolerate demanding, unreasonable, greedy bosses, continue to work for them even though they know full well of the bosses' shortcomings, but they would still stay on with the company and continue to serve the company. But when it comes to religion, once we see the archbishop or pastor as not what we expect them to be, we just leave.
