Politics and money, both already mentioned, are potent fuel for any "cause". People are really weird about the wolf thing. In some people's world view, contrary to what @Big Fin says, they are in fact shape-shifting unicorns with dazzles coming out the wazoo. I don't fault wolves for being killers, that's what they do. What I'm skeptical of is the politics and money cuz I know as well as anyone people twist facts around when they know their livelihood, in this case publishing studies about wolves, is at stake.
