As one of the posters above might say: blar, blar, blar.

There is no hypocrisy involved, imo. There is a LARGE difference between using animal products that are made into clothing and shoes and glues and what all after the animal is dead - everything dies eventually and the utilization of any or all of our parts will not harm us -and using that same animal before its death in a painful, uncaring, useless fashion that is brutalizing to it and to its practitioners alike.

Science on occasion will have to cause pain to some beings in order to prevent pain for some other beings. I understand that. But the "scientists" on this thread would be the first to concede that that there are experiments going on right now that are just plain silly with no reasonable end in view.
