Religion is a very personal thing..like Christianity. There are Christians and there are Christians..some in name, some in faith, some over zealous and overly religious,,its the middle ground and balance that is important. Just choose what suits you.. Look at Kong Hee followers,,its so obvious he is a false preacher but his followers are still so dumb as to follow him. what more can i say?
Look at Mad Khaw,,wear prayer beads etc,,,profess to be a buddhist but he has a heart of a serpent and mouth of a fox,,,need I say more?
Bottom line is as an individual one has to make the decision on what to follow...if one is a buddhist and see the monks being corrupt, does not mean that all is bad. One just have to follow the scripture and live life accordingly.
In all religions, there is always corruption, but that does not mean the religion itself is bad. Real followers can see this...
