why animals activities are against the present process of getting silk from the silkworm?

Animal rights activists are against the killing of any animal. Silk is woven from the cocoons of silkworms, which requires killing the silkworm. In this process, matured cocoons of silkworms are boiled to obtain pure silk reel. While boiling the silk larvae inside the cocoon will die. That is why this process is not supported by animal rights activists.
