I'm not so sure that I would regard the Vedas as scripture: there is so little of substance in them that to believe in them -- or the warlike religion they tout -- is decidedly unwise.
Truthfulness is to bring out the full case as it bears on an issue, not conceal material fact the way Hindus do.
The same goes for the equally warlike Koran and the warlike bunch that it misled. If we see the source of violence in the present world, it comes in between the warlike Hindus and Moslems.
Until they cease opening fire on each other, persecuting other faiths, and stirring up mindless hate, all based on outright lies, then I cannot say much for Hindu or Islam.
Come to think of it, neither can history. Any way you look at either one of these outlaw cults, they are just plain evil.
