RSPCA indirectly harms animals via occupying the top spot for animal welfare charity in the public consciousness and sucking up donations and resources whilst doing absolutely nothing to help or to rescue abused animals.
Every single time I have contacted the RSPCA to try and help an animal the RSPCA have redirected responsibility away to other agencies. The RSPCA is an immoral, money-grubbing company that exists off of animal cruelty.
