As human beings we are self aware and self judging beings. We have the privilege to exercise our free will to practice Ahimsa which has to be understood in terms of not absolute 'non-violence' but minimizing injury. Here in this interpretation we are not our body and hence causing harm to our own body has to be taken into account in minimizing injury. If a worm in our stomach is causing pain it has to be killed or the body will be killed. So practicing ahimsa does not mean keeping quiet. This principle has nothing to do with superiority or size of any manifestation.
Hindu thinking does not include a value of 'preserving' history. We deal with understanding universal and therefore timeless (and place-less) principles. Anyone making affirmative statements about what happened during Vedic times are purely expressing their belief system and therefore not subject to reason.
Ahimsa is mentioned as a value in Bhagavad Gita ( Chapter 13). It can be understood as a timeless principle.
There are some that believe that our Rishis ate meat and killed animals and they may cite all kinds of references.
I tend to think they are mistaken because principles taught when fully taken into *with the right context of other timeless principles taught* do not correctly justify those interpretations especially when Sanskrit words do have multiple meanings.
I am neither an expert in Sanskrit, nor in the verses of Vedas. However my thesis is that one does not need to have bookish knowledge of these verses to understand holistically timeless principles that are available for understanding here and now. We do not have to believe in teachings of any vedic statements. We need to understand and they have to make sense.
I think I came across this website perhaps by someone who posted a link here..I do not know have the knowledge to authenticate the interpretation. However I tend to favor studies that attempts proper interpretations of vedic citations often misused to propagate practice of 'animal sacrifices' in vedic times. I tend to favor such interpretations only because the timeless principles taught elsewhere are more in alignment then.
The site (and I have no knowledge to authenticate accuracy) is
MISCONCEPTION 3:- Violence against animals; meet eating, etc - VedicGranth.Org
There are typos by the writers and one has to overlook those things in reading through their interpretations.
In short it is our privilege to practice Ahimsa which is about making decisions by our free will to minimize injury recognizing that zero injury is not in the way nature works. It is one of the timeless 'Samanya Dharma' - available for understanding by any human being even if they are not well versed in any Vedic texts,
