Vegan Vixens

Joanna Lucas brought this site to my attention. I had never heard of the Vegan Vixens. I'm wondering what scantily clad women have to do with sparing animals pain, suffering, deprivation, confinement, and death. I'm not saying the women in question were coerced into participating, but aren't they being objectified—aren't their bodies being used—to make a point, and isn't that objectionable? Does the end of liberating animals justify sexist means? Would it justify racist or anti-Semitic means? Shouldn't one argue for liberation rather than appeal to people's emotions?
