Disappointed

I went to a couple sites targeting Christians curious about going veggie. Man they were disappointing. Very light and weak on the supporting theology. What really disappointed me was a verse from Isaiah 66 which goes on to say that killing an ox is like killing a man. Curious I looked at the whole chapter. On the surface the chapter is about the kind of worship G-d wants. In the same verse quoted, it goes on to say that grain offerings were as swine's blood. So nothing particularly against killing the ox.
