I think they will, but only once compelling meat substitutes become affordable. Even then, I think most of future society's condemnation will be for eating meat, not for animal experimentation. By comparison: When people talk about the holocaust, they are mostly referencing the mass slaughter, not the relatively small number of victims of human experimentation. (Wow, this got off topic quickly.)
