It has been noted that the composition of the movement may discourage the mobilization of particular demographics. A content analysis of magazine covers from highly visible animal rights organizations (PeTA and VegNews) revealed that most featured members were white, female, and thin. With this, and with the composition of the movement being mostly white, female, and thin, it has been suggested that animal rights media depict an activist ideal-type with such characteristics, and that this may mobilize thin white females while deterring others. Racialized, sexualized, and size-focused campaign tactics may also serve to deter potential members from joining the movement. Racialized tactics include the appropriation of African slavery and Holocaust language and imagery, and have been deemed insensitive and impugned by nonwhite communities. In addition, the movement has maintained racist stereotypes about nonwhite individuals' predisposition toward animal cruelty; these stereotypes arose in post-slavery U.S. and Britain, where nonwhites were deemed by law and by society to have a tendency toward animal cruelty. Sexualization of "ideal" women is used as a mobilization tactic, but reduces support for ethics-based campaigns and may be counterproductive, alienating women that do not have "ideal" body types. Sizeism is used as a tactic to frame veganism as a healthy and positive lifestyle, aligning with a popular association of fatness with moral failure. These tactics may contribute to gender inequality because unrealistic and sexualized representations of women are linked to their societal devaluation. Its lack of diverse membership may decrease the movement's legitimacy and ability to mobilize, as members of marginalized groups are more likely to mobilize when they are represented in the movement. An inclusive movement with strong group solidarity would decrease opportunity costs associated with participating (e.g., social stigmatization, lack of alternatives, legal persecution) and thus serve to increase and sustain participation in the movement.
