Animal rights is ultra pc, mostly lesbians with daddy issues and men who live on lentils types, ie weirdos.
They don't campaign against halal, most of these morons simply say all animal killing is the same. They even oppose the RSPCA.
Animal rights types are actually anti animal welfare.
A typical example is the millionaire celebrity Russell Brand. They are not logical people. Obviously stunning an animal is more humane then slitting its throat, and letting it bleed to death while conscious while Ismamic or Jewish rituals are observed. If you cut deeply and severe the spinal cord and brain step, ie almost decapitating that's a very fast death, but they don't they only cut the arteries.
