At least two Buddhist monks were injured Friday in a street clash in Cambodia's capital between two opposing groups of monks during a protest against Vietnam, which some monks accuse of suppressing religious freedom.
Historically, Buddhists have taught peace, love, serenity, etc. But as we can see from this, human nature has its limitations. In all religions and cultures, there are those that allow their anger to fuel rage and the rage, violence. This isn't just an American thing, although we bear our share. It's a global thing.
It's a mankind thing.
Addendum: You can see the pics here.
