I don't see why it shouldn't; the thread's been dead for a while.
If a mod disagrees, split the following.
The main issue I have with 'animal rights' (more specifically a ban on animal testing) is that it rests on the assumption that animals can undergo a state which can best be termed 'suffering' (ie detached from instant pain, and a reaction to that pain, but over a longer term), something which I haven't seen proven.
If you're opposed to it just because it has the capacity to cause pain, I don't see why that's any different to being opposed to checking computer software for bugs; (in evolutionary terms) they're both just error messages, and without some underlying intellect, they're meaningless.
