Why do you eat animal products? ; or, Why are you a vegan?

A question to everone. (Please feel free to write your response as a comment.)
To all persons eating animal products, wearing leather, fur, etc., or using animals in any other way: Why do you do this?

To all vegans: Why are you a vegan?
----
This is why I am a vegan:
I became a vegan - i.e. I stopped participating in all animal exploitation (including causing animals suffering by my food choices) - this autumn. It is the best decision that I have made. To show love, compassion and nonviolence to individuals of all beings truly transforms ones life. If we want to have true peace, we shouldn't inflict suffering to others. As we sow, so will we reap.

It think this is why everyone should become a vegan:
We should treat others as we want to be treated ourselves
All animals are conscious and they do value life as much as we do.
The following applies to all animals: humans, dogs, cats, cows, etc.:
If we don't want to be killed, we shouldn't kill other being.
If we don't want someone else to steal our family, we shouldn't steal their family.
If we want to find our purpose in this world, we shouldn't steal others purpose.
If we don't want to be exploited and abused, we shouldn't abuse anyone else.
If we don't want to become enslaved, we shouldn't keep anyone else as a slave.
If we don't want to hurt any animals, we must become vegans (i.e. stop eating, wearing and using animal products, and in other ways do actions that are hurting and killing animals).

If we love animals, we don't kill animals. We don't kill and eat anyone that we love. If we love animals, we must support their want to not be oppressed, including not to be killed.
I highly recommend this lecture: http://vimeo.com/17538152 and the book World Peace Diet by Will Tuttle (www.worldpeacediet.org )
