It matters not to me what holy writing a thumper thumps.
The problem with cutting a pasting little snippets of holy writings (the  Koran, the Bible, the Sutras or the Torah) is that they can and have  been used to justify any action the person chooses to be doing. They  make every action righteous. Thumping  clippings from the Bible made  Apartheid and the Holocaust  righteous, Thumping the Koran made flying  airplanes into buildings righteous, Thumping the Sutras made the rape of  China and the Aum terrorisms righteous.
Apartheid arose in the mind before the structures were built in society  to reinforce it, just like a temple is built when it arises in the mind.  Apartheid arose from the thought that others are beneath you and the  Bible was used to justify it.......obviously such an idea can be  ennobled  from the Sutra's as well.
The problem with lifting little sections of the holy writings to justify  your position is that pretty much anything can be justified in such a  manner. If you read the whole Bible, you get a different idea than from  "an eye for an eye"....or if you read the whole section that describes  homosexuality as a sin...you would also not eat pork, or shrimp or  lobster, your wife would be your property, and jerking off as much of a  sin as ......well never mind..... and almost any male (and most females)  are right there in sin with every gay or lesbian. The point being that  the thumper is using the writings to justify their position. They do not  care if that position is consistent with the rest of the writings, They  are not  looking for the way , they are only looking to justify their  way. Thumpers are are dangerous. When they are alone they are even more  scary, because there is no check at all on how crazy they can  become...there is nowhere for them to get a sanity check....but then  again..a thumper does not thump to have their ideas tested in crucible  of a discussion, they thump to justify their position, their reality,  created by their ideas. When challenged a thumper has nothing to  say....all they can do it thump some more, and use some stolen wisdom to  try and justify their own position, because by nature, a thumper has no  wisdom of their own.
Before we get all holier then thou and pat ourselves on the back, we are  all thumpers at times too, just like we all are pretentious sometimes  too.  A wise person recognizes this tendency in themselves, and works to  minimize it in themselves rather then maximize the danger to themselves  and others. A wise person gets a sanity check from those around them  from time to time, just to make sure they have not wandered too far afield.
Before we get too down on ourselves for our tendency to wander off the  path all too easily, let us remember that all do this sometimes as well.  We also are sometimes wise, and sometimes noble as well. There is  nothing that arises in any person, be that nobility or ignorance, that  does not arise in us as well. To pretend otherwise is just lying to  ourselves. Every decent Zen teacher I have ever met has someone they  respect to check themselves with so they do not wander off too far  afield in their life. Power corrupts, a wise man or woman gets a check  on this corruption from time to time.
Wisdom is not ignoring anything...ignoring anything is ignorance.  Ignoring it in others is not kind, ignoring it in ourselves is dangerous.
English is a tough language...there is no pronoun for the you that is  me, and the me that is you, because it is really different then "us". Us  is more our separate beings gathered together. The big "I" includes you  and the big "you" includes me. When anyone calls anyone on anything,  they are indeed calling themselves on it at the same time...there is  nothing we dislike more in others, then what we dislike in ourselves.  Ask anyone who has lived with a former smoker, a former drinker, a  former addict, a former intellectual, a former anything.
The point here is ..no one is beneath us...they are exactly us. No  matter how much we huff or stomp away, or use the sutras to justify our  position, the basic point of the whole thing (any holy writing) has been  missed the moment we think we can leave. The moment the thought arises  that there is indeed a they that is not us, that can be left, we are  lost. One of the basic points of Jesus' teaching was that he was exactly  the beggar you treated poorly, he is exactly the "homo" or the  "terrorist" you deny basic human rights to. (oh wait..we already did  that to him didn't we??? wow...Deja Vu all over again.....) He is  exactly the "least of my brothers "(what ever you do to the least....  you do him...exactly).....hmmm  a most Buddhist of teachings........None  of us is alone in missing these teachings, most of us miss them most of  the time. Whatever we do to anyone, we do at the same time to Buddha,  Jesus, Mohamed, Bahula, Moses, Shiva, Zeus, The goddess, the green man,  to Hitler, Pol Pot, the republicans and the democrats.
Be Well
