I don't like your "holier than thou" attitude towards vegans.
The aim of these pages is not to put anyone down, and we're very sorry if that's how you feel. We applaud the sentiments of all reasonable, thoughtful, caring people who are upset about the current state of world affairs and want to do something about it. At the same time, our mission is to promote Krishna consciousness as a practical and time-honored solution to not just one problem, but all the world's anomalies.
Anyone who drives a car is implicated in the exploitation and pollution of the earth. The same is true for anyone who owns anything made of plastic or any other by-product of the petroleum industry. Anyone wearing clothing manufactured under harsh conditions is implicated in the workers' suffering. Anyone who buys bananas or chocolate from a supermarket is implicated in the harsh conditions under which their farmers are forced to exist. Anyone wearing diamonds is supporting the hellish conditions within diamond mines. The list of ways in which we're implicated in others' suffering is quite long; just by breathing or drinking water we unknowingly kill other living beings.
If we want freedom from the cycle of suffering—which we're part of, just by existing in this world—we can either attempt to address all these issues individually or try to find the single underlying cause of all suffering and deal with that. Krishna consciousness aims at uprooting the core problem of material existence as a whole—our forgetfulness of the Supreme Person.
While this may sound simplistic, its implications are far-reaching. For example, if I truly and completely understand myself and all other living creatures to be eternally integral, infinitesimal parts of an infinite, supremely conscious, omnipotent, and supremely benevolent person—who's the ultimate source of all energies and who has made perfect arrangements for our well-being—I may likely experience such a level of contentment and peace that I won't want to cause suffering to anyone else or greedily consume that which isn't mine.
This is precisely the attitude of a Krishna conscious person; everything comes from Krishna, everything has its use in Krishna's service, and since everyone is part and parcel of the Supreme Person, everyone without exception deserves life, liberty, and the pursuit of happiness.
That indeed is a "holy" state of mind—and it's easier to talk about it than experience it—but the process of Krishna consciousness is practical, direct, and has a profound effect on the way we see and act on the world. All the most noble aims of veganism, humanitarianism, communism, free trade-ism, or any other ism, can be most completely achieved through the simple and straightforward practice of bhakti-yoga, Krishna consciousness. Believe it or not.
"Everything animate or inanimate that is within the universe is controlled and owned by the Lord. One should therefore accept only those things necessary for himself, which are set aside as his quota, and one should not accept other things, knowing well to whom they belong." (Sri Isopanishad, Mantra One)
