Are you presupposing the non existence of Culture/Tradition/Religion/History/Identity and their influences on people in the west?
Or are you saying that Culture/Tradition/religion ect ect are not Part of the entity which we term as "West"?
No to both questions.
The evidence is required from those who claim that "Western Translators", are not influenced by biases ect.
No such claim was made on this thread. Please re-read the posts.
If you are familiar with Indian scripture, you will know that most ancient texts are interpreted in the context of commentaries. This is practically the only way to make sense of texts such as sutras (for their brevity) and the Rig-Veda (for its archaic language). Sayana's commentary - the most well known medieval commentary on the Rig-veda is viewed as an Advaita commentary owing to his own affiliation to the doctrine (he was Vidyaranya's brother). Madhva wrote a partial commentary, which was elaborated by Raghavendra - both of which align with Tattva-vada.
Neither of the above will accept the other's version. How then, does one expect a universal Hindu translation or commentary? It appears that there is the impression that a translation is somehow better if it is made by a Hindu - regardless of his views - than by a non-Hindu, even if he has no known biases. Besides prejudice, there is no justification for this line of thinking.
Note that Griffith mostly follows Sayana in his translation. So, if we want to assign bias to Griffith, it should be on the grounds that he provided an Advaitic translation.
Because the Rig-veda was never meant to be read and indeed, that is still the traditional view. It is to be chanted (by Dvijas only) with the right Swaras and this is not something one learns by reading the text. As for its content, it contains very little in the way of philosophy and religious insight. The ten books are collections of prayers (and eulogies) to a set of gods who were prominent during its time, but whose importance diminished a long time ago. While we can find a number of people who claim that the Rig-Veda is the bedrock of Hinduism, challenge them to show how much of it is part of their religious practices and they will struggle for an answer. This is because the role of the Rig-Veda in the living Hindu tradition is almost non-existent.
The level of knowledge about the content of the four Vedas is abysmal among Hindus. For instance, a few months ago, we had people on this forum who claimed that the Yajur Veda taught mathematics! The OP is a muslim and has likely been misinformed that the Rig-Veda is the Hindu equivalent of the Quran/Bible. We are not willing to learn or put in the effort, and yet, we are ready to voice objections against Westerners who make an attempt to provide us with translations and other forms of research.
