This thought is shared by people that would at the same time agree with the following stance : inflicting suffering and death on other beings for unnecessary reasons is wrong. None of us would try and compromise with this idea.
We all think that what this dentist did to Cecil the lion is wrong. Because he killed an innocent being for pleasure.
The huge majority of people think that corrida or dog fighting are barbaric practices. Because these animals are used for entertainment.
Most of us get offended by celebrities wearing massive fur coats. Because we all know the suffering that these animals go through and we know these people could be wearing something else.
In other words, we all agree that pleasure, habits or convenience are not good enough reasons to hurt someone or take their life.
Now, let's take a moment and try to see how these habits aren't different from following a nonvegan lifestyle.
Eating animal products not only is unnecessary, we now have thousands of medical articles out there proving that it's actually detrimental to our health.
Using animal skins for fashion taste -be it leather, wool, silk or fur- isn't anywhere near being a necessity. Going to Sea World, to the zoo or to the circus isn't exactly vital either.
Now, the only practice that could be seen as necessary is vivisection. Yet, most people are against vivisection and think it's cruel. Why is that? Because when we think with our hearts, we see things the way they are : using other beings, enslaving them and torturing them, even for reasons that could be seen as potentially necessary, isn't right. And it's easy to stand up against something that doesn't affect us emotionally or personally like the food you've been taught to eat or the clothes you enjoy wearing do.
Being against dog fighting or vivisection is the natural inclination of our hearts and souls, but these practices are in every way similar to those of eating the corpses or secretions of beings that have been enslaved and killed for our own palate pleasure (or fashion taste; or amusement).
Our true nature is to feel compassion for other beings, especially the vulnerable, and to protect them from suffering.
The fact that people we love (parents, grandparents, uncles, aunts, friends) brought us up eating certain foods or wearing certain clothes or going to the zoo to feed the monkeys has interfered with our natural compassion radar.
But as we grow older and make decisions based on our sense of justice every day of our life, shouldn't we all take the time to redefine what morality means to us and how we want to live by it?
We were all born vegan. None of us was born drinking the milk from another species or drooling at the sight of another living being.
If we really want to be as superiorly intelligent as we claim to be as a species, shouldn't it be by living by the ethics we all claim to have? Shoudn't that involve sowing the peace and justice that we seek to reap? Shouldn't that mean respecting and protecting the earth that nourishes us and that we'll return to?
