The dominant terms currently employed by vegan animal advocates - and this has been the case for several years now - are "animal cruelty," "animal abuse," and "animal abuser." Jeremy Hess has suggested that, as a result, a "linguistic gap" has developed between the way most people talk and think about such terms and the way vegans talk and think about them.
Cultural speciesism has its own way of thinking about words such as animal "cruelty" and animal "abuse." Most people, in their sedimented cultural understandings of these terms, which in turn is reflected by traditional animal welfarism in the shape of, for example, the RSPCA, are certain that they are neither cruel nor abusive to other animals. Many of the people vegans will label as cruel to other animals, or as "animal abusers," will regularly speak out against animal cruelty and abuse; they will sign petitions about these issues, and volunteer at animal shelters in order to deliberately shield other animals from these things. Vegans may have good reasons to think that such people are "cruel animal abusers" - but the dominant socially- and generationally-transmitted culture says that they are not. Emphatically not.
Such terms are culturally restricted, largely, to the treatment of those other animals used as pets but will often spill over to other areas of animal use if "unnecessary suffering" is caused or is involved. Cultural speciesism says that the standard use of other animals is simply not cruel and is not abusive. If vegans want to shift the paradigm on this, they need to recognise that they are using established welfarist language in this conversation, and not the language of animal rights. We have to acknowledge that welfarists and speciesists "own" these terms, so to speak, in order to talk to them about changing their definitions of them.
It does little good to simply call people "cruel" or "abusers" because those accusations are culturally incoherent and create this "linguistic gap" between speciesist people and vegan advocates. Speciesists and welfarists have "owned" these terms for many generations, so banally calling such people names that their culture flatly refuses to see them as, is futile. If we are going to insist of continuing to use RSPCA words and phrases, then we must accept that they are overwhelmingly defined by the orthodox - and not in the way vegans would like.
If activists and activist groups insist on complaining that RSPCA or Red Tractor welfare standards, for example, are being ignored, they will do well if they fully embrace the fact that their claims - and the ways that their claims are generally understood and reported - are from within the welfare paradigm.
