Umm...Soma is not alcohol. There are many theories on what it is, and I have my own theory, but it is most definitely not alcohol. I just had to point this out in your post because the real Soma has a very interesting history.
Anyway, I'm really not interested in a continued religious quibble. It is a fact that hunting and meat eating were widespread in Vedic and hindu society, and it is a fact that the spread of jainism and buddhism coincided with the spread of vegetarianism. I am perfectly aware of their dietary laws as well, and the fact that Buddhists do eat meat. But my point was that ahimsa was not a central tenet of hinduism (it is for jainism), and that meat eating was not due to hinduism initially.
Now the larger point is this - religious laws do not matter for somebody who chooses not to follow them. Whether I eat beef or meat or not is not influenced by what a religious scripture states. Even if the first sentence of the Rig Veda and all Puranas was "Thou shall not eat beef because verily, cow is the most blessed amond animals" or some such crap, I would still eat my hamburger and fries if I like it.
Neither the vedas, nor the manusmriti nor the quran are part of the Indian penal code. So I will have a beer if I feel like it, I will have a burger if I feel like it.
Soma was an intoxicant and an possibly a hallucinogenic similar to Shamanic Plants used throughout history by various cultures, African or red Indian.
No knowledgeable Hindu will say that ahimsa is a central tenet of Hinduism, especially since both their main maha-purans called the Ramayana and Mahabharat deals with all kinds of violence and prescribes violence to address certain non dharmic activities. (especially when everything else fails)
A hindu is asked by his religion to protect the cows and as such it will fall within his rightful religious duty to attack you or anybody for killing a cow. It is his dharma.
So you can either choose to kill cows and start a riot or ban it and help establish peace and prosperity by sacrificing a unnecessary greed. Or do you wish to push the religious sentiments of the Hindus to pander to your spiteful ego and then find out what they are capable of ???
