don’t know anything about this group...but not all animal protection activists are loonies. The NAVS group I dontate to because they make the differentiation about when and how to use animals in science that makes sense.
sometimes, it is counterproductive and behind the scientific times to do animal experiments...it actually hinders our knowledge. So I take all this with a grain of salt and try to find out what the group stands for, instead of accepting them at face value or denouncing them if I don’t know them.
There’s a lot of info in the first link in this article about the PCRM, it’s worth reading.
