I think you may be confused about “the true Christian way.” To not eat animal flesh is a personal decision, but I think you’ll have a hard time proving God/Jesus forbid eating meat. In fact, there are many Bible passages that prove otherwise.
I do think fighting animals for fun is sickening.

There are also Bible passages which says an eye for an eye.....is revenge okay according to the Bible?
