Not all pagan/wiccan sects have the same standardized practices you know, some of them like the hallal, jews and other tribal societies, still follow what they consider to be the old path in their rituals over politically correct contemporary practices.[/QUOTE]

I have never heard about that before.

But it is true that pagan beliefs are very diverse, but IME blod sacrifice is extremely rare. But if they do, of course that should also be forbidden!

As for sacrificing your own blod or parts of yourself, I do not see that that has a bearing on the topic of animal abuse.
