The reason why there is animal abuse at all is because of us regarding animals as property, which will remain as long as people insist to inflict unnecessary suffering and death upon animals for palatable pleasures or convenience. It is well known that animal products are unhealthy, and that a vegan diet is healthy: http://www.adelicatebalance.com.au/
as long as you permit this and participate in this, you are apart of
the animal abuse (and also guilty of the most horrendous parts of the
abuse, which you enable by endorsing the property status of animals),
instead of a part of the solution.

Regarding health, did you know that milk products are unhealthy: http://drmcdougall.com/misc/2007nl/mar/dairy.htm
