in reply to There's much more people in sin here ...
In these Monastery walls there is no 'sin', sin implies a belief in a religion or a true right and wrong.
The Monastery is a place of public consumption where some people chose to respect others and treat them with some level of reserve so as not to anger or instigate a negative reaction. While some choose to always respond or use what may seem to the majority as a negative tone, that is still left to personal preference.
It takes a small person to ridicule or constantly evoke negative emotions, but it takes an even smaller person to allow them to succeed.
