Intolerant - Sometime because of fear, fear of going astray, as if thinking free, or otherwise, or questioning religion, as well as religious culture is an act of devil or hell bound mind. This is the reason why most of us Muslims remain silent even when an inhuman or unethical act been done in the name of religion or religious culture IMO.
Another reason is because of greed, greed for being purist as par one's holly book, gaining more holly points, and as such, as if all other things and meaning on this world means next to zero. As if all other wrongdoings, or wrong in other meaning will be ignored by God because of those holly points that gained. This is why IMO again, people mob up as saviour of religion, or religious culture even doing inhuman act or killing other people.
